JFrame.setSize(int, int) - how set window dimensions?

Question

Hello,
In my simpliest swing apps I can't set window dimensions by setSize(int, int). What am I doing wrong?
//v 1.3
import javax.swing.*;   
public class HelloWorldSwing {
    public static void main(String[] args) {
        JFrame frame = new JFrame("HelloWorldSwing");
        final JLabel label = new JLabel("Hello World");
        frame.getContentPane().add(label);
     frame.setSize(200, 200); //won't change anything??
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
}

Answer 1

.pack() is resizing the frame. Move setSize() after it.
