Does Not Override Abstract Method actionPerformed(ActionEvent) Error Despite Having Method

Question

EDIT: Thanks to all who pointed out the typo! However, I am still having issues with my timer. For some reason, the timer is not causing the window to be repainted after every second. Edited code is posted below!

I am having trouble compiling the following code- I get the two errors:

C:\java>javac Project2.java
Project2.java:8: error: Project2 is not abstract and does not override abstract
method actionPerformed(ActionEvent) in ActionListener
public class Project2 extends Applet implements ActionListener
       ^
Project2.java:19: error: <anonymous Project2$1> is not abstract and does not ove
rride abstract method actionPerformed(ActionEvent) in ActionListener
        ActionListener getNewValues = new ActionListener() {
                                                           ^
2 errors

The purpose of the program is to simulate a race between a tortoise and a hare. A random number generator is used to determine how many moves forward or backward the tortoise and hare can move at any given turn.

    application.setSize(2600, 300);
    application.setVisible(true);

I have the method actionPerformed so I am not sure why I am getting the error that I am getting. Any feedback or help would be much appreciated!

You have a spelling mistake in actionPerformed, you missed r. Change to:

public void actionPerformed(ActionEvent e)  
{
     repaint();
}
