Error In Mouse Listener Program

I am learning java and while doing a MouseListener problem I am facing an error in the class declaration, tried everything known to me please help me out.
According to me I have done all the coding correctly, Pasted the code in IDE too but getting the same error.

Thanks

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

public class Sub extends JFrame		
{
	private JPanel mousepanel;
	private JLabel statusbar;
	
	public Sub()
	{
		super("Mouse Events");
		// we didnt have a FlowLayout as we had in previous programs
		
		mousepanel = new JPanel();
		mousepanel.setBackground(Color.WHITE);
		add(mousepanel, BorderLayout.CENTER); //BorderLayout used instead of FlowLayout and it will place it in the center of the window.
		
		statusbar = new JLabel("Default");
		add(statusbar, BorderLayout.SOUTH); // same as above
		
		thehandler handler = new thehandler();
		mousepanel.addMouseListener(handler);
		mousepanel.addMouseMotionListener(handler);
		
                private class thehandler implements MouseListener, MouseMotionListener
		{
			public void mouseClicked(MouseEvent event)
			{
				statusbar.setText(String.format("Clicked at %d, %d", event.getX(), event.getY()));
			}
