==Memory Management==
==Memory Management==
The Java programming language is based on [[Object Oriented programming]] principles, coupled with [[garbage collection]]. This means, unlike [[C]] and other lower level programming languages the developer is able to create programs without worrying about pointers, references and memory. Instead the Java [[Virtual Machine]] is able to manage objects that are in use, periodically deleting objects that are no longer referenced (and therefore no longer required by the program).

== Example Code ==
=== Hello, World ===
The easiest program in any language is something that displays "Hello, World!".
<pre>package hello;
public class world
{
public void Main(String[] args) { System.out.println("Hello, World!"); }
}</pre>
=== GUI with JFrame ===
An example of creating and showing a JFrame with nothing in it:
<pre>JFrame frame = new JFrame();
frame.show();</pre>
