Hello world,
I just want to know for JFrame is there a possible way of removing the close(the cross) in the frame. I mean like 'setResizable(false) for not allowing the frame to resize.
Thank you..

Which Java version you are using?
If you are using JDK 1.4 or above, try setUndecorated(true) method (I have never tried, check it out).
If you are using versions below 1.4, then you have to use JWindow instead of a JFrame.
