Java GUI Framework Interview Question:

How to get the screen size? How Do I center a window on the screen?

Submitted by: Administrator

Manually, pre 1.4:

Use java.awt.Toolkit.getDefaultToolkit().getScreenSize() to get the screen size, and do the math:

import java.awt.*;
Dimension winSize = win.getSize();
Dimension screenSize =
Toolkit.getDefaultToolkit().getScreenSize();
win.setLocation(
screenSize.width / 2 - winSize.width / 2,
screenSize.height / 2 - winSize.height / 2
);

Since 1.4:

Window.setLocationRelativeTo(null);
