public static void startTimer() {
listener = new ActionListener() {
@Override
public void actionPerformed(ActionEvent event) {
System.out.print("action");
timerLabel.setText("" + seconds);
seconds--;
System.out.println(seconds);
if (seconds < 0){
System.out.print("zero");
wrong();
}
}
};
displayTimer = new Timer(1000, listener);
displayTimer.setInitialDelay(1);
displayTimer.start();
if (right == true){
System.out.print("true");
displayTimer.stop();
right = false;
seconds = 30;
displayTimer = new Timer(10000, listener);
displayTimer.setDelay(10000);
displayTimer.setInitialDelay(1);
displayTimer.start();
}
else if (right == null){
System.out.print("null");
displayTimer.stop();
seconds = 30;
displayTimer = new Timer(10000, listener);
