Java Awt components are displayed but Swing components are not displayed in Applet

Question

I am trying to run a very simple Java applet program. When I used AWT.Label component, I can see the component through appletviewer. The code I am using is:

import java.applet.Applet;
import java.awt.Graphics;
import javax.swing.*;
import java.awt.*;

public class AppletTest extends Applet
{

  Label user = new Label("Username", Label.LEFT);

    public void paint(Graphics g) 
    {
     g.drawString("Registration Form", 195, 10);
    }

     public void init()
     {
       add(user);
     }

 }

When I use swing.JLabel component, I cannot see any component on the screen except for Registration form printed on top:

import java.applet.Applet;
import java.awt.Graphics;
import javax.swing.*;
import java.awt.*;


public class AppletTest extends JApplet
{

  JLabel user = new JLabel("Username", JLabel.LEFT);

    public void paint(Graphics g) 
    {
     g.drawString("Registration Form", 195, 10);
    }

     public void init()
     {
       add(user);
     }

 }

What is the issue?

Answer 1

Because paint is a method in JApplet , when you override it, you need to call super.paint(g) so that the parent component can still do it's painting. Your paint method should look something more like this:

@Override
public void paint(Graphics g) {
    super.paint(g);
    g.drawString("Registration Form", 195, 10);
}
