I tried to put a if statement but it doesnt working.

Static int gScore = 1000;
t = new Timer(100, new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        score01.setText("score: " + gScore);
        gScore--;     
    }
});
t.start();
t.setRepeats(true);
if(gScore== 970){//A
    t.stop();
    t.setRepeats(false);    
}//A

i want to stop the timer when it reach to a given value and remove it inside the JFrame

Answer 1

Your timer shall be final

t.cancel();
t.purge();

and when declaring your timer, set it as final

final Timer t = new Timer(...)

Answer 2

You should change your code as followed:

static int gScore = 1000;
final Timer t = new Timer(100, new ActionListener() {
  public void actionPerformed(ActionEvent e) {
    score01.setText("score: " + gScore);
    gScore--;
    if(gScore== 970){//A
      t.stop();
    }//A
  }
});
t.start();
