Java Buttons Help

[an_mui]

1. Write a program that will change a label's colour each time a button is pressed (use at least 5 colours)

I don't know why but the background colour does not show up. Can someone please help me?

package button1;

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

public class button1 extends JApplet implements ActionListener
{
JButton mybutton;
JLabel label;
static int counter =0;
JFrame frame1 = new JFrame ("first name");

public void init()
{
JLabel label = new JLabel (" ");
label.setSize(300,300);
label.setBackground(Color.blue);
label.setOpaque(true);

mybutton = new JButton ("Press me!");
mybutton.addActionListener(this);

Container contents = new Container();
contents.setLayout(new FlowLayout());
frame1.setSize(300,300);

contents.add(label);
contents.add(mybutton);
frame1.getContentPane().add(contents);
frame1.setVisible(true);
}

public void actionPerformed (ActionEvent e)
{
counter++;
if (counter ==2)
{
label.setBackground(Color.red);
}
else if (counter==6)
{
JLabel Message = new JLabel ("End of Program");
Container message_container = new Container ();
message_container.setLayout(new FlowLayout());
message_container.add(Message);

JFrame message_frame = new JFrame ("End of Program");
message_frame.setSize(300,300);

message_frame.getContentPane().add(message_container);

frame1.setVisible(false);
message_frame.setVisible(true);
}
}
}

First of all, let's clean this up so it can be read. Code tags are your friend.

Also, it's good to adhere to Java naming conventions, which frown on the use of underscores.

code:

package button1; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class Button1 extends JApplet implements ActionListener {         JButton myButton;         JLabel label;         static int counter = 0;         JFrame frame1 = new JFrame("first name");         public void init()         {                 JLabel label = new JLabel(" ");                 label.setSize(300,300);                 label.setBackground(Color.blue);                 label.setOpaque(true);                 myButton = new JButton("Press me!");                 myButton.addActionListener(this);                 Container contents = new Container();                 contents.setLayout(new FlowLayout());                 frame1.setSize(300,300);                 contents.add(label);                 contents.add(mybutton);                 frame1.getContentPane().add(contents);                 frame1.setVisible(true);         }         public void actionPerformed (ActionEvent e)         {                 counter++;                                 if (counter == 2)                 {                         label.setBackground(Color.red);                 }                 else if (counter==6)                 {                         JLabel message = new JLabel("End of Program");                         Container messageContainer = new Container();                         messageContainer.setLayout(new FlowLayout());                         messageContainer.add(message);                         JFrame messageFrame = new JFrame("End of Program");                         messageFrame.setSize(300,300);                         messageFrame.getContentPane().add(message_container);                         frame1.setVisible(false);                         messageFrame.setVisible(true);                 }         } }
