Code:
import java.awt.Dimension;
import javax.swing.*;
public class Game extends JFrame {
private static final long serialVersionUID = -7919358146481096788L;
JPanel a = new JPanel();
public static void main(String[] args) {
new Game();
}
private Game() {
setTitle("Insert name of game here");
setLocationRelativeTo(null);
setLayout(null);
setDefaultCloseOperation(EXIT_ON_CLOSE);
a.setPreferredSize(new Dimension(600, 600));
add(a);
pack();
setVisible(true);
}
}
So I set the preferred size of the JPanel
to 600 by 600 and pack the frame, but the frame's size is still 0 by 0.
Why is this and how do I fix it?
