Error at class name

[Ryan Bishop]

Hi,

This code is directly from Swing: A Beginner's Guide by Herbert Schildt (page 31). I'm using Eclipse and keep getting an error on
line 10 saying "The type JTextField must implement the inherited abstract method ActionListener.actionPerformed(ActionEvent)."

I don't know what that means or what I should do.

import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;


class JTextFieldDemo implements ActionListener{             //error here for JTextFieldDemo
	
	JTextField jtf;
	JLabel jlab;
	
		
	JTextFieldDemo()  
	{
		JFrame jfrm = new JFrame("A Text Field Example");
		jfrm.getContentPane().setLayout(new FlowLayout());
		jfrm.setSize(240, 90);
		jfrm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		
		jtf = new JTextField(10);
		jtf.addActionListener(this);
		jfrm.add(jtf);
		jlab = new JLabel("");
		jfrm.getContentPane().add(jlab);
		jfrm.setVisible(true);
	}
	public void actionPeformed(ActionEvent ae) {
		
		jlab.setText("Current contents: " + jtf.getText());
	}
	
	public static void main(String args[])
	{
		SwingUtilities.invokeLater(new Runnable() {
			public void run() {
				new JTextFieldDemo();
			}
		});
		
	}
		
	}

It means the JTextFieldDemo class should have a method called actionPerformed, not actionPeformed
