Java must know the location of any package or packages or group of classes that you are going to call during the execution of an application, with the exception of the normal Java runtime class libraries. The three options to using Java classpaths are to set the entire classpath on the command line ( java -cp [paths] classnames), set the classpath in the environment (export CLASSPATH=path1:path2...) or to run java from the root class directory that you are using. I'm not going to get into jar file names and packages etc, because that's a whole nuther tutorial.
My recommendation is to acquire a good book, or more, on Java. The Core Java Vol.1 book covers extensively how to run Java with various classpath definitions, and it's an excellent primer. There are other good books out there too numerous to mention.

What is the error you are getting when you try to run your java program?

Could you explain a little bit clearlier (howtos), I don't know about
that classpath thing.

I think this would be better suited in a java discussion list, but depending on the error you get, make sure the classes your app needs are availabie in your classpath.

Subject: Running Java in Linux Terminal
I'm using NetBeans as the Java editor now. But I can't run any program in Terminal (by typing java -cp ....). I don't know what I need to be able do
that. In my school, I don't need to modify anything in the Java class,
just
type java -cp . <File> and run . Please tell me what I lack.
(I hit "man java" but no command for java found)
