import javax.swing.Timer;
import java.awt.event.ActionListener;
public class SwingTimer{
Timer stopwatch;
int count = 0;
int delay = 1000;
//startTimer(60); this is how to instantiate the timer method for 60 secs
public void startTimer(int countPassed){
ActionListener action = new ActionListener(){
public void actionPerformed(ActionEvent e){
if(count == 0){
stopwatch.stop();
lblTimer.setText("You're out of time!");
}else{
lblTimer.setText("You have " + count + " seconds remaining");
count --;
}
}
};
stopwatch = new Timer(delay, action);
stopwatch.setInitialDelay(0);
stopwatch.start();
count = countPassed;
