The first thing you have to do is to make a icon with width=16px and height=16px.
Import the image in a ImageIcon-object in your application.
Then you just call the method setIconImage() on your Frame.
//example
MyFrame.setIconImage(MyImageIcon);

//tm.setIconImage();
}

}
It's showing the following error
Error: (101) method setIconImage(javax.swing.ImageIcon) not found in class TestMenu.

Hi Murli,
u need to change the line,
tm.setIconImage(frameIcon);
to
tm.setIconImage(frameIcon.getImage());
it will work.
