Code:

javac file.class

Of course, you have to have Java SDK (software developement kit) installed and configured in order to be able to compile anything.

Also, you don't compile class files. You compile java files into class files. That would be like putting toast into a toaster.

Code:

javac TestClass.java

Will compile the java file into TestClass.class (assuming the java file contained the line "class TestClass"). You can then run:

Code:

java TestClass

so long as the TestClass.java file has a main() function defined

That's right, sorry for the mix-up....

but since we're on the topic of java:

How do you compile into .jar ??
What are the diferences to compiling to .class? (besides the number of files=)

You don't compile into a jar. You compile a bunch of class files into a directory heirarchy. Then you zip them up into a jar. That's right, jar is just zip. Try it sometime. 'unzip /usr/local/jdk1.3.1/demo/jpda/examples.jar'.

Best,

Samuel
