LocalTime minus() method in Java

Java 8Object Oriented ProgrammingProgramming

An immutable copy of a LocalTime where the required duration is subtracted from it can be obtained using the minus() method in the LocalTime class in Java. This method requires two parameters i.e. the duration to be subtracted and the TemporalUnit of the duration. Also, it returns the LocalTime object with the required duration subtracted from it.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.time.*;
import java.time.temporal.*;
public class Demo {
   public static void main(String[] args) {
      LocalTime lt = LocalTime.now();
      System.out.println("The LocalTime is: " + lt);
      System.out.println("The LocalTime after subtracting 3 hours is: " + lt.minus(3, ChronoUnit.HOURS));
   }
}

Output

The LocalTime is: 07:04:25.562
The LocalTime after subtracting 3 hours is: 04:04:25.562

Now let us understand the above program.

First the LocalTime is displayed. Then an immutable copy of the LocalTime where 3 hours are subtracted from it is obtained using the minus() method and this is displayed. A code snippet that demonstrates this is as follows −

LocalTime lt = LocalTime.now();
System.out.println("The LocalTime is: " + lt);
System.out.println("The LocalTime after subtracting 3 hours is: " + lt.minus(3, ChronoUnit.HOURS));
