Oracle plans to ship OpenJDK builds to make it easier for developers to deploy Java applications to cloud environments. To make it easier for developers, Oracle also plans to open source commercial features previously only available in the Oracle JDK. In this session learn more about the plans to open source a number of Oracle JDK commercial features as part of the OpenJDK offering. Bernard Traversat is the Vice President of Development for the Java SE Platform at Oracle. He manages the development team responsible for the Java Language, JVM, Core libraries, Java UI toolkits, and Java deployment stack for Oracle JDK product. He is also overseeing security development for the Java platform and OpenJDK development. https://developer.oracle.com/ https://cloud.oracle.com/en_US/tryit

Oracle Corporation and about Java
 
01:26
Oracle Corporation is an American multinational computer technology corporation headquartered in Redwood Shores, California. The company specializes primarily in developing and marketing database software and technology, cloud engineered systems, and enterprise software products — particularly its own brands of database management systems. In 2015, Oracle was the second-largest software maker by revenue, after Microsoft Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture. As of 2016, Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.

Java Source File Structure
 
18:27
Java is a programming language. It was first developed by James Gosling at Sun Microsystems, which is now a part of Oracle Corporation. It was released in 1995 as a part of Sun Microsystems' Java platform. The language has developed much of its syntax from C and C++. Java applications are usually compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM). Java is currently one of the most popular programming languages being used. It has about 10 million users. Java was developed to achieve 5 main goals. These are It should be simple, object-oriented, distributed and easy to learn. It should be robust and secure. It should be independent of a given computer architecture or platform. It should be very performant. It should be possible to write an interpreter for the language. The language should also support parallelism and use dynamic typing. There are many types of Java programs which run differently: Java Applet - small program written in Java and that is downloaded from a website and executed within a web browser on a client computer. Application - executes on a client computer. If online, it has to be downloaded before being run. JAR file (Java ARchive) - used to package Java files together into a single file (almost exactly like a .zip file). Servlet - runs on a web server and helps to generate web pages. Swing application - used to build an application that has a GUI (windows, buttons, menus, etc.). EJB - runs on a web server and is used to develop large, complex websites. Java is commonly used to teach students how to program as a first language, yet is still also used by professionals. Java requires that each variable be initialized. Some older languages such as C, allow variables to go uninitialized, which can cause random failures with mysterious bugs. Java requires that each method that declares a return type, always return a value. This also prevents bugs. Java comes with a large set of classes and methods, the Java API that can be used without having to develop as much code "from scratch". Unlike C, Java primitive types, such as int, are always the same size in the number of bits which helps achieve cross-platform compatibility. Java used to be thought of as being slower than C, but that's less important in recent years with computers being faster. Java has exception-handling that requires a programmer to handle error-conditions such an Input/Output errors. Code compiled on one Java platform can be run on other platforms that support Java without modification of either the source-code nor the byte-code. For example, this means that a person can make a Java program for a Windows computer and have it run a Linux computer or a Mac computer.

Java Tutorial - Compiling and Running Java Programs using Command Prompt and Unix Terminal
 
05:01
Watch in 1080p HD for optimal clarity! All commands used are listed below for your convenience. In this video I demonstrate through the use of screen captures and narration how to compile and run Java programs using the Windows Command Prompt and the Ubuntu Unix Terminal. No IDE is required for the compilation and execution process - compilation and execution can be performed via the Command Prompt and the Terminal. I'll also demonstrate how to install and set up the Oracle Java Development Kit (JDK) on Windows and Ubuntu systems, as well explain briefly what a JDK is. To compile and run Java programs, we require the Java Compiler, the Java Virtual Machine and the Java Standard Library, all of which are included in the JDK, hence the JDK is absolutely essential for our purposes. I hope you learn something new from this video tutorial, and if you like it, please like, comment and subscribe! ----- Download Link for JDK ----- Download x64 installer if your system is 64-bit, and download x86 installer if your system is 32-bit. http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html Check Operating System for Windows: Control Panel - System and Security - System Check Operating System for Ubuntu: Settings - System Details ----- Commands for Windows ----- Updating PATH Variable - Append to End of Value: ;C:\Program Files\Java\jdk1.7.0_25\bin Moving to Directory Containing Source File - Type into CMD: cd [Path of Directory Containing Source File] Compiling Program - Type into CMD: javac [source file name].java Running Program - Type into CMD: java [source file name] ----- Commands for Ubuntu ----- Delete OpenJDK - Type into Terminal: sudo apt-get purge openjdk-\* Move to Downloads Folder - Type into Terminal: cd ~/Downloads Create New Directory for JDK Installation - Type into Terminal: sudo mkdir -p /usr/local/java Move Installer into New Directory - Type into Terminal: sudo mv [installer file name].tar.gz /usr/local/java Move to New Directory - Type into Terminal: cd /usr/local/java Extract Installer - Type into Terminal: sudo tar xvzf [installer file name].tar.gz Open Profile File - Type into Terminal: sudo gedit /etc/profile Update PATH Variable - Append to End of File: JAVA_HOME=/usr/local/java/jdk1.7.0_25 PATH=$PATH:$HOME/bin:$JAVA_HOME/bin export JAVA_HOME export PATH Inform System of New JDK - Type into Terminal: sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jdk1.7.0_25/jre/bin/java" 1 sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/java/jdk1.7.0_25/bin/javac" 1 udo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/java/jdk1.7.0_25/jre/bin/javaws" 1 Set JDK as Default - Type into Terminal: sudo update-alternatives --set java /usr/local/java/jdk1.7.0_25/jre/bin/java sudo update-alternatives --set javac /usr/local/java/jdk1.7.0_25/bin/javac sudo update-alternatives --set javaws /usr/local/java/jdk1.7.0_25/jre/bin/javaws Reload PATH Variable - Type into Terminal: . /etc/profile Move to Directory Containing Source File - Type into Terminal: cd [Location of Directory] Compile Java Program - Type into Terminal: javac [File Name of Source File].java Run Program - Type into Terminal: java [File Name of Source File] ----- Programs Used for Production ----- Camtasia Studio 8 (Screen Capture) Sony Vegas Pro 12.0 (Video Editing) Audacity (Noise Removal) Microsoft PowerPoint (Slideshow) ----- Credits ----- Intro Template Obtained From: http://www.ravenprodesign.com/ Background Music: The XX - Intro ----- References ----- http://docs.oracle.com/javase/7/docs/webnotes/install/windows/jdk-installation-windows.html http://docs.oracle.com/javase/7/docs/webnotes/install/linux/linux-jdk.html http://www.skylit.com/javamethods/faqs/javaindos.html http://www.wikihow.com/Install-Oracle-Java-on-Ubuntu-Linux

Java Development Kit 8 - Java SDK 8 Oracle
 
03:40
How to set up Java Development Kit 8 - Java SKD 8 Oracle The video tutorial teaching all the necessary set to set up your Java development environment. Java is leading the world from web applications to smart phone devices like android. Java is everywhere. The quicker you shift to learn this wonderful language the better equip you will be ahead of the game. Java is a strongly type language which means that all variables type must be declared first before you. When you use the Java compiler to convert your java file into a JVM (Java Virtual Machine) executable the compiler will turn your code into bytecode. Java does not support pointers like very popular languages like C and C++. This is because of security issue with accessing the memory location which can lead to exploits. Even worst can bypass the firewall is code memory location is known. In the tutorial I begin by referencing the Java website to set up the base. Then I refer to the source development kit to start creating and compiling your own code. The compiler makes use of the javac “FILENAME.java” command to run the compiler. If you need to know the current java version running on your machine use the java -version command inside of command prompt. Once we have installed the basic’s in the video then I go ahead and show you an example program that we can write and run. I used the text editor of notepad ++ to accomplish this task. I have placed a download link below if you would like to use it as well. https://java.com/en/ http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html https://notepad-plus-plus.org/ Source code used in the video for the Java File class HelloYoutubers{ public static void main(String args[]){ System.out.println(hold()); } public static String hold(){ return "Hello Youtubers"; } } Thank you for watching this video and being a part of the YouTube community.

Full Speed Ahead! Ahead of Time Compilation for Java SE
 
50:22
David Buck, Principal Member of Technical Staff, Oracle One of the lesser-known features coming with JDK 9 is experimental support for ahead-of-time (AOT) compilation. Compiling Java bytecode into ready-to-execute machine code before runtime means that many applications may benefit from quicker startup and, in the case of multiple JVM instances, even lower memory consumption. In this demo-heavy session, you will see what advantages AOT has to offer and, perhaps even more importantly, what its limitations are. You will also get the opportunity to see Java’s new AOT compilation in action and leave with the knowledge needed to experiment on your own later. Although Java’s AOT is not yet ready for production use, this is a great chance to get a sneak peek at one of HotSpot’s most exciting new technologies.

PL/SQL: Collections Part-2
 
07:51
In this tutorial, you'll learn what are the collection types and its attributes PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

83 Advanced Java | JDBC 4 | without using Class forName(-) oracle thin driver | adv java
 
12:36
Advanced Java Tutorail : JDBC 4 0. adv java | Java Database Connectivity JDBC Application to test the database without using Class.forName(-) method. JDBC 4.0 Specification: The important feature of JDBC 4.0 specification is automatic loading of java driver class from java.sql. Driver File available from jar file of jdbc driver i.e. (ojdbc6.jar in oracle 11g). This makes programmers to avoid Class.forName(-) statement in his java application while writing jdbc code. - All the jdbc drivers thar are given based on jdbc 4.0 specification are giving java.sql.Driver File in there jar files, So when these jar files are added to the classpath the driver manager class automatically collects the driver class from java.sql.Driver File, loads the driver class & registers that driver automatically with DriverManager service. ojdbc14.jar (given by oracle 10g) is based on jdbc 3.0 specification so it does not contain java.sql.Driver File . ojdbc6.jar (given by oracle 11g) is based on jdbc 4.0 specification, so it contain java.sql.Driver File as shown below java.sql.Driver------oracle.jdbc.OracleDriver postgresql-8.4-701.jdbc4.jar of posgresql is based on jdbc 4.0 specification, so it contains java.sql.Driver File as shown below java.sql.Driver------org.postgresql.Driver JDBC application to test the connection with oracle database without using Class.forName(-) ===================================================== Step 1) Set the jar to the classpath ( ojdbc6.jar) Step 2) create the jdbc application import java.sql.*; public class WithoutClassForName { public static void main(String[] args) throws Exception { Connection con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl", "scott", "boss"); Statement st=con.createStatement(); st.executeUpdate("insert into student values(1000,'patil','Omerga')"); } } compile & run

http://www.codeinpractice.com Hi, This is the tutorial will tell You the Steps of Compiling and Running a Java program you don't need to understand the code just now. All you need to take away from this Video is the following 3 Things: 1. All code is written in classes (the body of a class is defined in the starting and closing curly brace { } ) 2. Code that we need to run will be inside the main method.This is the method that is the starting point of all programs 3. Name of the file is the name of the class that has the main method followed by the .java suffix. Capitalization Matters, so Hello is not the same as hello These steps are the same for compiling and running almost all java programs Thank You for viewing Please Rate and Subscribe.

Let's start learning Java from basic questions like what is Java tutorial, Core Java, where it is used, what type of applications are created in Java, why use java and Java platforms etc. Our Java tutorial helps you to learn Java with easy and simple examples. This free java tutorial for complete beginners will help you learn the java programming language from scratch. visit Source Newboston playlist: https://www.youtube.com/watch?v=Hl-zzrqQoSE&list=PLFE2CE09D83EE3E28 Java is a general-purpose, high-level programming language developed by Sun Microsystems. The Java programming language was developed by a small team of engineers, known as the Green Team, who initiated the language in 1991. The Java language was originally called OAK, and at the time it was designed for handheld devices and set-top boxes. Oak was unsuccessful and in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web. Later, in 2009, Oracle Corporation acquired Sun Microsystems and took ownership of two key Sun software assets: Java and Solaris. Today the Java platform is a commonly used foundation for developing and delivering content on the web. According to Oracle, there are more than 9 million Java developers worldwide and more than 3 billion mobile phones run Java. In 2014 one of the most significant changes to the Java language was launched with Java SE 8. Changes included additional functional programming features, parallel processing using streams and improved integration with JavaScript. The 20th anniversary of commercial Java was celebrated in 2015. Java is an Object-Oriented Language Java is defined as an object-oriented language similar to C++, but simplified to eliminate language features that cause common programming errors. The source code files (files with a .java extension) are compiled into a format called bytecode (files with a .class extension), which can then be executed by a Java interpreter. Compiled Java code can run on most computers because Java interpreters and runtime environments, known as Java Virtual Machines (VMs), exist for most operating systems, including UNIX, the Macintosh OS, and Windows. Bytecode can also be converted directly into machine language instructions by a just-in-time compiler (JIT). In 2007, most Java technologies were released under the GNU General Public License. #Java on the Web Java is a general purpose programming language with a number of features that make the language well suited for use on the World Wide Web. Small Java applications are called Java applets and can be downloaded from a Web server and run on your computer by a Java-compatible Web browser. Applications and websites using Java will not work unless Java is installed on your device. When you download Java, the software contains the Java Runtime Environment (JRE) which is needed to run in a Web browser. A component of the JRE, the Java Plug-in software allows Java applets to run inside various browsers Java Tutorial from Basics to Advance,java basics for beginners,advanced java tutorial,Java Programming Tutorial,java tutorials for beginners,java programming tutorial for beginners,Java Tutorial for Beginners,java,java programming,java programming for beginners,java tutorials,java (programming language),java video tutorial,java strings,advanced java tutorial for beginners,learn java programming examples,java programming for beginners tutorial #JavaTutorial #Javaprogramming
