I'm trying to draw a red square and a blue square but treat them as though they are individual components. Code below shows only the red square, but when the line frame.getContentPane().add(redAy) is commented out the blue square appears. Can anyone tell me what is going on and how to make both squares appear?
Thanks!
import javax.swing.*;
import java.awt.*;
//-------------------------- blue -----------------------
class BlueAyComp extends JPanel{
int x = 0;
int y = 0;
int w = 0;
int h = 0;
public BlueAyComp(int ulx, int uly, int width, int hite){
x = ulx;
y = uly;
w = width;
h = hite;
setForeground(Color.blue);
}
public void paintComponent(Graphics g) {
g.drawRect(x, y, w, h);
}
}
//--------------------------- red ----------------------
class RedAyComp extends JPanel {
int x = 0;
int y = 0;
int w = 0;
int h = 0;
public RedAyComp(int ulx, int uly, int width, int hite){
x = ulx;
y = uly;
w = width;
h = hite;
setForeground(Color.red);
}
public void paintComponent(Graphics g){
g.drawRect(x, y, w, h);
}
}

public class classtest{
public static void main(
String arggs[]){
JFrame frame = new JFrame("Class Test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(500,400);
frame.setBackground(Color.white);
JPanel blueAy = new BlueAyComp(40, 40, 30, 30);
JPanel redAy = new RedAyComp(200,200,30,30);
frame.getContentPane().add(blueAy);
frame.getContentPane().add(redAy);
frame.show();
}
}
