  {
     Container tiger = getContentPane ();
     tiger.setLayout ( new FlowLayout ()  );
     
     
     die1Label = new JLabel( "Die 1");
     tiger.add (die1Label);

>> implements ActionListner

Wrong spelling

public class CalcRate extends JApplet implements ActionListener {

Not the solution you were looking for? Getting a personalized solution is easy.

Ask the Experts
>> rollButton.addActionListner (this);

rollButton.addActionListener (this);
