I am a Android studio beginner. May I ask how can I get the timestamp in android studio through Firebase in String?

The code that I have used for updating the timestamp as below. 

  Map<String, Object> map = new HashMap<>();
  map.put("timestamp", ServerValue.TIMESTAMP);                                  
  queue.child(UserInfo).updateChildren(map);

Big thanks!!

You can do it:

public class MyTimeStamp {
    private Object timestamp;

    public MyTimeStamp() {

    }

    public Object getTimestamp() {
        return timestamp;
    }

    public void setTimestamp(Object timestamp) {
        this.timestamp = timestamp;
    }
}
And so:

public static void start(Context context) {
    MyTimeStamp timeStamp = new MyTimeStamp();
    timeStamp.setTimestamp(ServerValue.TIMESTAMP);

    Log.d(TAG, "start: ", timeStamp.getTimestamp().toString());
}
