You are supposed to write the lines javac Helloworld.java and java Helloworld in the command line.
javac Helloworld.java compiles your .java file which has your code. It creates a .class file for you.
java Helloworld runs the class file
You must using the command line go to the bin folder in which you have java.exe and javac.exe. You should also have your Helloworld.java file here. After that you can write those 2 commands in the command line.
You say you use JCreator, never used it but atleast the Eclipse IDE got a button with which you can run your code. Also i hope you got the HelloworldFrame class otherwise that wont compile. [ April 23, 2006: Message edited by: Jon Mattson ]
