1//deprecated in main thread:
2try {
3  Thread.sleep(1000);//time is in ms (1000 ms = 1 second)
4} catch (InterruptedException e) {e.printStackTrace();}

6//please use bellow instead:
7Timer timer = new Timer();
8timer.schedule(new TimerTask() {
9  @Override
10  public void run() {
11    //what you want to do
12  }
13}, 1000);//wait 1000ms before doing the action

1// Sleep 1 second
2TimeUnit.SECONDS.sleep(1);
3// Sleep 1 minute
4TimeUnit.MINUTES.sleep(1);
