Hi There,
You can achieve your functionality by setting the size of the JFrame(setSize(Dimension d)).
Use this Method of JFrame as setSize(Dimension dim), pass the Dimension object in this method. Before this create the Dimension object in this way.
JFrmae frame=new JFrame();
Dimension dim=new Dimension(Toolkit.getScreenSize());
This will create your JFrame of your screenSize i.e maximized.
I hope this will solve your problem....

Hi Sanjay,
using the above code i will get a frame which is of the full screen size. i am working on the windows platform, and when i want to maximize, i want to take into consideration the windows taskbar(start menu). that is, the maximize should work the same way as would a normal windows application.
also, if a user clicks on the maximize icon on the frame, i get the desired result. i want to get the same result from an event generated thru the program itself.

You need to use JNI to do this. JDJ has written several articles on how this can be accomplished, and in fact, there is a utility called JUtil that you can download to make this stuff easy. Check it out.
I agree. Here's the link:
