Question

We would like to know how to format date time as '[14:30:53]'.

Answer

import java.time.LocalTime;
//from www. j  a  v a  2  s.  com
public class Main {

  public static void main(String[] args) {
    System.out.println(getTime());
  }

  public static String getTime() {
    return String.format("[%s:%s:%s]", zeroOne(LocalTime.now().getHour()),
        zeroOne(LocalTime.now().getMinute()), zeroOne(LocalTime.now()
            .getSecond()));
  }

  public static String zeroOne(int second) {
    if (second < 10) {
      return "0" + second;
    }
    return String.valueOf(second);
  }
}
