Java SE (Java Platform, Standard Edition)

I there a way to make the jframe bigger than the screen dimensions (800 by 800) to say 1200 by 800.

I used netbeans to create a JFrame. I was using a laptop of screen size 1200 by 800 and I positioned my components according to those dimensions using grouplayout. Now when I run it on my desktop on lesser screen size the JFrame is truncated and I can see n operate on only 3/4 of the width. I have some buttons at the bottom right corner of the screen which I cannot totally see.

Is there a way to make the JFrame to appear completly (Bigger than the screen size)

Thanks in advance
