Java Files

• File.java
  All Java source code is named by a file with the extension of .java
• Name.class
  For each class defined in your code, the java compiler will produce a file called Name.class where Name is the name of a class. It is convention to name your main class application or applet the same as the base filename in which it is contained. (e.g. you have a class called SayHello, then it should be stored in a file called SayHello.java)
• You can have at most one class in a file that is public!! This must have the same name as the filename it is contained in.

Example Code

• Hello World Example
