Where to open

I have a java program, and it opens in the top left of the screen.

This is expected, but how do I change that?

Can I, as with HTML, set it to open at a percentage of the height and width?

Thank you in advance for your help.

Is it a swing (standalone application)?

How do you launch it?

Post more details please.

Yes, it is standalone. The pertinent script to be changed to achieve these ends, I do believe, is found here:

import javax.swing.*;

public class Main {

public static void main(String[] args) {
startGUI go = new startGUI();
go.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
go.setSize(200, 100);
go.setVisible(true);

}

}

Do this:


import javax.swing.*;

public class Main {

public static void main(String[] args) {
startGUI go = new startGUI();
go.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
go.setSize(200, 100);

//This line will center the JFrame in the screen
go.setLocationRelativeTo(null);

go.setVisible(true);

}

}
