The following example is an implementation of the Producer-Consumer problem. A class which provides the methods for generating and consuming an integer value is separated from the Producer and the Consumer thread classes. class SharedData { int data; synchronized void set(int value) { System.out.println("Generate " + value); data = value; } synchronized int get() { System.out.println("Get " + data); return data; } } class Producer implements Runnable { SharedData sd; Producer(SharedData sd...

Design Patterns in PHP : Singleton Design Pattern
By Rakhitha Ratnayake, 14 December 2009.
Singleton design pattern is the most simple design pattern which has only one class. Singleton design pattern allows only one object to be created from a singleton class. If many other classes need to use a object from a singleton class, they have to use the same instance. These types of classes are required for logging, registry, database connections, memory manager, window manager…etc. This... Read Full Story
I got interested in this book after discovering Gary Rosenzweig’s AS3 tutorials on his Flash Game University Website. I was impressed by his ability to explain things clearly and simply. As other reviews have already stated “AS3 Game Programming University” is an excellent and highly readable book for learning AS3. In practice I find it much more helpful than Colin Moock’s book “Essential ActionScript 3.0″, which is a little too academic for me (although I’m glad I have it!). I’m also... Read Full Story

Thread(Runnable target, String name) Creates a new Thread object with the specified name and based on... Read Full Story
A thread refers to a single sequential flow of control within a program. For simplicity, think of threads as processes being executed within the context of a certain program. Consider modern operating systems that allow you to run multiple programs at once. While typing a document on your computer using a text editor, you can listen to music at the same time and surf through the net on your PC. The operating system installed in your computer allows multitasking. Likewise, a program... Read Full Story
The top-level containers like JFrame and JApplet in Swing are slightly incompatible with those in AWT. This is in terms of adding components to the container. Instead of directly adding a component to the container as in AWT containers, you have to first get the content pane of the container. To do this, you'll have to use the getContentPane method of the container. Java Programming Tutorial Sample Source Code: Setting Up Top-Level Containers: A JFrame Example: import javax.swing.*; import... Read Full Story
