I would like to have a JLabel changint color to a random one, while jumping to a random position, and while changing its text.

but the setText and setBounds seem to clash and i don't know why. if you comment out the setText then the setBounds will work, but they won't work together.

import java.awt.*;
import java.util.*;
import javax.swing.*;

public class test2 extends JFrame { 

private static JLabel label = new JLabel("0");
private static Random gen = new Random();

public test2() {
    JPanel panel = new JPanel();
    panel.add(label);
    this.add(panel);
}

public static void move() {
    for (int i = 0; i < 10; i++) {
        int n = gen.nextInt(254)+1;
        int nn = gen.nextInt(254)+1;
        int nnn = gen.nextInt(254)+1;
        label.setText(""+i);
        //the setBounds command will not work with the setText command. why?
        label.setBounds(n*2, nn*2, 20, 20);
        label.setForeground(new Color(n, nn, nnn));
        try {
            Thread.sleep(200);
        } catch (Exception e) {}
    }
}

public static void main(String[] args) {
    test2 frame = new test2();
    frame.setVisible(true);
    frame.setSize(600, 600);
    frame.setResizable(true);
    frame.setLocationRelativeTo(null);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);   
    move();
}
}
