Period plusMonths() method in Java

Java 8Object Oriented ProgrammingProgramming

An immutable copy of the Period object where some months are added to it can be obtained using the plusMonths() method in the Period class in Java. This method requires a single parameter i.e. the number of months to be added and it returns the Period object with the added months.

A program that demonstrates this is given as follows:

Example

 Live Demo

import java.time.Period;
public class Demo {
   public static void main(String[] args) {
      String period = "P5Y7M15D";
      Period p1 = Period.parse(period);
      System.out.println("The Period is: " + p1);
      Period p2 = p1.plusMonths(2);
      System.out.println("The Period after adding 2 months is: " + p2);
   }
}

Output

The Period is: P5Y7M15D
The Period after adding 2 months is: P5Y9M15D

Now let us understand the above program.

First the current Period is displayed. Then an immutable copy of the Period where 2 months are added is obtained using the plusMonths() method and this is displayed. A code snippet that demonstrates this is as follows:

String period = "P5Y7M15D";
Period p1 = Period.parse(period);
System.out.println("The Period is: " + p1);
Period p2 = p1.plusMonths(2);
System.out.println("The Period after adding 2 months is: " + p2);
