A Simple Java Applet
An Applet is a small program that can be sent across the Internet and interpreted on a client machine. To give permission for remote access it must be a public class. Typically it is a class that inherits and/or defines a special set of functions needed to run an applet. These are part of the class Applet. So all Java applets are public classes that extend Applet.
You can not run a Java applet unless it is also an application or you have a WWW page that refers to it.
The page needs HTML like the following to call the compiled code, in the same directory:
Here is a suitable piece of HTML to test a simple HelloWorld class:
The code for the HelloWorld applet has to be a public class called "HelloWorld" that extends Applet and is in in a Java file called:
Here is the Java code:
The Applet is compiled just like any other program:
This will generate a set of files with extension/suffix ".class". Notice that the compiler forces you to name the file "HelloWorld.java", the Class "HelloWorld", and generates the binary bytecode in a file called "HelloWorld.class". Sun has written a special program to test applets in page:
However you can not use 'java' to run the HelloWorld class - it has no 'main'. Neither can 'java' "run" the WWW pages like the test.HelloWorld.html file.
