testing for backspaces?

[Dillinger4]

I have a little program that traps keystrokes. But when the person backspaces i get returns instead of the cursor being placed one space back thus letting the user correct mistakes. Any idea what would be the bet route to go? Shoud i trap for the BackSpace button too?

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

   class CatchType extends KeyAdapter{
       public JTextArea jta;       
       public JTextField jtf; 

       public static void main(String[] agrs){
        new CatchType();    
         
    }

     public CatchType(){
         JFrame jf = new JFrame("Typing Test");
         jta = new JTextArea();
         jtf = new JTextField();
         jta.setFont(new Font("Informal Roman", Font.BOLD, 44)); 
         jta.setLineWrap(true); 
         jta.setBackground(Color.black);
         jta.setForeground(Color.red);
         Container c = jf.getContentPane();
         c.setLayout(new BorderLayout());
         c.add(jta, BorderLayout.CENTER);
         c.add(jtf, BorderLayout.SOUTH);
         jf.addWindowListener(new WindowMonitor());
         jtf.addKeyListener(new Keyboard()); 
         jf.setSize(450,300);
         jf.setVisible(true);  
     }      
             
   
     class Keyboard extends KeyAdapter{
     
      public void keyPressed(KeyEvent ke){
       Character text = new Character(ke.getKeyChar());
       jta.append(text.toString()); 
     }
   }
 }
