    Default Move button with mouse pressed

    Hello guys.
    I'm new here.
    I have a problem with my java programming and i'm wondering if you can help.

    Write a class (called W6P1.java) that will create the following interface:
    3 buttons (one, two, three).
    Tips:
    - Set size to (300,100);
    - Use FlowLayout as the layout manager

    Add action listeners to the left button <one> and the right button <three> and add code to rotate the labels of the buttons every time a button is pressed. If the left button is pressed the labels rotate to the left (from <one>, <two>, <three> they will become <two>, <three>, <one>, press it again and they become <three>, <one>, <two>; press it for a third time and they become as before <one> <two> <three>.
    Similar operation is required when the right button (<three>) is clicked but this time the rotation will take place right-wise.

    I have done this:
    import javax.swing.*; 		//for everything that is Jxxx
    import java.awt.*; 			//for FlowLayout
    import java.awt.event.*;	//for the actionlistener
     
    public class W6P1 extends JFrame implements ActionListener
    {
    	private JButton btn1;
    	private JButton btn2;
    	private JButton btn3;
     
     
    	public W6P1()
    	{
    		super("Work6Part1");
    		btn1 = new JButton("One");
    		btn2 = new JButton("Two");
    		btn3 = new JButton("Three");
     
    		btn1 = new FlowLayout(FlowLayout.RIGHT);
     
    		setLayout(new FlowLayout());
     
    		add(btn1);
    		add(btn2);
    		add(btn3);	
     
    		ButtonHandler handler = new ButtonHandler();
     
    		btn1.addActionListener(handler);
    		btn2.addActionListener(handler);
    		btn3.addActionListener(handler);
    	}
    	public static void main(String[] args)
    	{
    		W6P1 window = new W6P1();
    		window.setSize(300, 100);
    		window.setVisible(true);
    		window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    	}
     
    	//create the inner class
    	private class ButtonHandler implements ActionListener
    	{
    		public void actionPerformed(ActionEvent e)
    		{
    			if (e.getSource() == btn1)

    I'm really confused what to do next.
    Anyone can help me?

    Thanks in advance,

    Stavros
