it says public SwingApplication.Java not declared, i'm using freeware JCreator by the way, i can't copy and paste the error when i use javac in dos prompt even in JCreator.

JCreator had an 'capture output' option, when I used it years ago.
And if you compile on Dos you simply send the output (stdout and stderr) to a file:

javac SwingApplication.java > compile.log 2> compile.err

It isn't SwingApplication.Java - is it?

Maybe this make no sense, but I'd try writing the fully qualified name of the interface you implement, ie, implements java.awt.event.ActionListener.
