Java Daemon Thread vs User Thread Example
 
05:51
What is a Java Daemon Thread? A daemon thread is a type of java thread that does not prevent the JVM from exiting when the program finishes. The Java Virtual Machine exits only when all threads running are all daemon threads (I.e. No Java User Threads exist). The initial java main method is a user thread and a thread will automatically inherit the daemon status of its parent (Creator) thread. Any threads created from the main thread will also be user threads unless you specifically call the thread#setDaemon(true) method. For example: T1 is a daemon thread, when T1 creates and starts T2, T2 will also be a daemon thread. Also, worth mentioning When the JVM terminates, daemon threads: - Finally blocks are not executed - Stacks are not unwound – JVM exists. To make a daemon thread, the setDaemon(true) must be invoked BEFORE the thread is started. Garbage collector is an example of a daemon thread. I.e. As you are aware, the garbage collector thread will not prevent the JVM from exiting when all your user threads die. I hope you enjoyed this quick Java tip!! Sub & See you next time!!

Java101: Master the java.util.Scanner Class!
 
19:11
The Java Scanner class is the bane of every computer science student taking their first Java programming class. Why do Java programming instructors love this class so much? One reason is that it provides a simple way to prompt the user for input so you can write simple programs while you learn basic Java syntax. Or they're just monsters who want to torture you. Either way, the Scanner class is a part of every Basic Java Programming class. In this video I'll show you how to master the Scanner. I'll show you three different versions of the program, each slightly more complex than the one before it that shows how to: * Use the Scanner * Get input from the user - One coin denomination at a time - All coin denominations on a single line * Handle errors that arise when the user does not cooperate Scanner Javadoc: https://docs.oracle.com/javase/8/docs/api/java/util/Scanner.html Save/Import Eclipse Preferences: https://www.youtube.com/watch?v=o_zQPwGeaAk Subscribe to my channel: https://www.youtube.com/channel/UCAoqQ5DnRyLisPdzUodMrww Source code link: https://github.com/makotogo/Scanner101 Check out my blog: http://makotoconsulting.com/blog Follow me on Twitter @jstevenperry

Java Heap Dump Analysis - VisualVM Tutorial
 
04:43
In this tutorial I show you how to use VisualVM to perform a Java Heap Dump snapshot in a live executing Java application in eclipse IDE. Ahem… Let me ask…First….What is Java VisualVM? Java VisualVM is a tool that provides a visual interface for viewing detailed information about Java applications while they are running on a Java Virtual Machine (JVM), and for troubleshooting and profiling these applications. This includes objects allocated on the Heap, Thread state, Execution environment information, Stack etc. Great for debugging dog slow applications!! Ok cool, now what is a Heap Dump? A heap dump is a snapshot of the memory of a Java Process at a single point in time. This contains data about Java objects, classes in the heap, class, fields, references, class loader names, static content, Thread Stacks etc. And... Why would I create a Heap Dump? There are many, but here are my two favourites. When performing performance analysis on an application, performing a heap dump during certain execution phases will provide you will critical information on the state of the Java Process, such as object allocation on the heap and thread states. Second, when an application crashes due to a Java java.lang.OutOfMemoryError, you can enforce the JVM to perform a snapshot and capture the application’s state via a heap dump. This heap dump will typically be placed into a java_pid*[id].hprof file. You can then load the heap dump file into a visualizer to understand the java applications state – this provides a good insight and clue into why the program crashed. Although if your application is running on a cloud based ephemeral file system this may be tricky. But the majority of applications that require a heap dump for analysis are most likely not in the cloud and rather dedicated high performance data centers. Last one… You mentioned compressed Oops, whats that? Ill create another video but read this for now chum. http://docs.oracle.com/javase/8/docs/technotes/guides/vm/performance-enhancements-7.html Don’t forget to subscribe for more tech content! Cheers!

String Buffer and String Builder - Explained | Java9s.com
 
09:38
http://java9s.com StringBuffer and StringBuilder objects are useful when we need to frequently append content or modify the content which are as Strings. Because Strings are immutable, every modification will endup creating new String objects which will overload the Memory. So, when you need to modify the String, it is better to use String Buffer or String Builder. In this video, i have explained the differences between the String Buffer and String Builder and demonstrated with an example how they behave.

WebLogic Advanced JMS: Unit of Work
 
10:44
Sr. Principal Product Manager for App Grid, Jeff West, discusses an advanced feature in WebLogic for JMS called Unit Of Work and provides a demo of UOW in action. Many applications need an even more restricted notion of a group than provided by the Message Unit-of-Order (UOO) feature. If this is the case for your applications, WebLogic JMS provides the Unit-of-Work (UOW) Message Groups, which allows applications to send JMS messages, identifying some of them as a group and allowing a JMS consumer to process them as such. For example, an JMS producer can designate a set of messages that need to be delivered to a single client without interruption, so that the messages can be processed as a unit. Further, the client will not be blocked waiting for the completion of one unit when there is another unit that is already complete. To see how to set up the project and check out the code, check out this video: http://www.youtube.com/watch?v=-LRKasiAlpA For more information about Unit of Work please see the online WebLogic documentation here: http://download.oracle.com/docs/cd/E12840_01/wls/docs103/jms/uow.html

Highly Available JMS with WebLogic: Store and Forward Client
 
12:50
WebLogic offers two kinds of Store and Forward configuration: WebLogic-to-WebLogic and Java client-to-WebLogic. With the Store and Forward client you can have a standalone Java client that can reliably send messages to a WebLogic server. In the case that a remote JMS destination is not available, messages will be stored on the client machine in a JMS FileStore and then sent to the remote WebLogic server once it is available again. To see how to set up the project and check out the code, check out this video: http://www.youtube.com/watch?v=-LRKasiAlpA For more information, see the WebLogic documentation for this feature here: http://download.oracle.com/docs/cd/E12840_01/wls/docs103/client/saf_client.html

Introductory step-by-step guide how to use & set-up the Eclipse Java VisualVM plugin IDE integration. This also works for Spring Tool Suite (STS) and other eclipse IDE based distributions. Java Profiling Tools. What is VisualVM? Java VisualVM is a tool that provides a visual interface for viewing detailed information about Java applications while they are running on a Java Virtual Machine (JVM), and for troubleshooting and profiling these applications. This includes monitoring objects allocated on the Heap, Memory, Thread state, Execution environment Information, HeapDumps, Stack etc. Great for debugging dog slow applications!! Who would use a Java Profiler like VisualVM? Everyone! But especially anyone wanting to optimise their applications performance! This will identify heavily used methods, objects, Perform Heap Dumps, GC info and much more! Again, great for debugging dog slow applications! Guide: a) Download Eclipse Plugin. (Link below). b) Extract ZIP archive into any directory (D) c) Add local update site as directory (D) and select & install VisualVM Launcher. d) Ensure Launcher global preferences point to VisualVM and your JDK. e) Launch the java application with the new VisualVM Launcher. f) View your live java execution in VisualVM. Don’t forget to subscribe for more tech content! Cheers!

WebLogic Advanced JMS: Unit-of-Order
 
09:35
Sr. Principal Product Manager for App Grid, Jeff West, discusses an advanced feature in WebLogic for JMS called Unit Of Order and provides a demo of UOO in action. Message Unit-of-Order is a WebLogic Server value-added feature that enables a stand-alone message producer, or a group of producers acting as one, to group messages into a single unit with respect to the processing order. This single unit is called a Unit-of-Order and requires that all messages from that unit be processed sequentially in the order they were created. To see how to set up the project and check out the code, check out this video: http://www.youtube.com/watch?v=-LRKasiAlpA For more information about Unit of Order, please see the online WebLogic documentation here: http://download.oracle.com/docs/cd/E12840_01/wls/docs103/jms/uoo.html
