// that you declared in Task 1

// Part 5 student code ends here.

// ***** Task 4:
// create a private inner class that implements ActionListener
// your method should identify which of the 3 buttons
// was the source of the event
// depending on which button was pressed,
// call the setUpGame method of the Game class
// with arguments 3, 4, or 5
// the API of that method is:
// public void setUpGame(int nSides)
// At the end of the method call validate()
// Part 4 student code starts here:
public void actionPreformed(ActionEvent ae)
{

game = new Game (3);
else if(ae.getActionCommand(). equals (\"4-by-4\"))

}
// Part 4 student code ends here.
