Android Studio: Reset CountDownTimer

I have a timer that counts down from 10, when it reaches zero it makes a random imageview in an array turn visible. I just want this timer to reset itself every time it reaches zero. How can I Achieve this?

Current Attempt:

public class rear_gunner extends AppCompatActivity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_rear_gunner);
    View view2 = findViewById(R.id.item_frame);
    final ImageView enemy1 = (ImageView) findViewById(R.id.enemy1);
    ImageView enemy2 = (ImageView) findViewById(R.id.enemy2);
    ImageView enemy3 = (ImageView) findViewById(R.id.enemy3);
    ImageView enemy4 = (ImageView) findViewById(R.id.enemy4);
    //sets screen orientation on created
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

    view2.bringToFront();
    final ImageView[] enemies = new ImageView[4];
    enemies[0] = enemy1;
    enemies[1] = enemy2;
    enemies[2] = enemy3;
    enemies[3] = enemy4;


    Random rand = new Random();
    int n = rand.nextInt(20) + 1;

    CountDownTimer countDownTimer = new CountDownTimer(10000, 1000) {
        @Override
        public void onFinish() {
            Random rand = new Random();
            int n = rand.nextInt(3) + 1;
            enemies[n].setVisibility(View.VISIBLE);
        }

        @Override
        public void onTick(long millisUntilFinished) {

        }

    };

    countDownTimer.start();
}


}

Any help or advice to improve the code here would be greatly appreciated thank you.

Create object CountDownTimer outside OnCreate() then .start() again that object after your random is done inside onFinish()

CountDownTimer countDownTimer;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    countDownTimer = new CountDownTimer(2000, 1000) {
        @Override
        public void onFinish() {
            //what you want to do after CountDownTimer is done
            countDownTimer.start(); //start again
        }

        @Override
        public void onTick(long millisUntilFinished) {

        }

    };

    countDownTimer.start();
}
