Mike,

against the two previous postings,
it's not necessary in your main method to save the reference of the new
object in a variable.
I tried your code, and it works fine!
You simply made a typical JBuilder newbie mistake:
JBuilder doesn't know that it shall execute the main method of this class.

I took this way to use your class - not that this would be the way I would
recommend also for you to work with JBuilder:
1) I created a new project
2) In this project I created a new application named "uebung_3". JBuilder
also allows (leads) me to create a frame by this.
3) Now i Have an application clas with main method and a JFrame class. Look
at the code and figure it out - will help you very much!
4) Since I wanted to try your class, a combination of main method and frame,
I deleted the generated Frame, and I replaced the code of the application
class by your code.
My class uebung_3 is simply your code, only additional 1 package command at
the top.

Compiles and executes - all ok.

In fact JBuilder gives you great help, but everything must be in a project,
and you should let it generate application and frame like I showed you.

Finally: Please follow that advice to call your class Java-typical: Uebung3.

Hope this helps you to get a Java crack.

Regards,
Hartmut
