Period plusDays() method in Java

Java 8Object Oriented ProgrammingProgramming

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

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.plusDays(5);
      System.out.println("The Period after adding 5 days is: " + p2);
   }
}

Output

The Period is: P5Y7M15D
The Period after adding 5 days is: P5Y7M20D

Now let us understand the above program.

First the current Period is displayed. Then an immutable copy of the Period where 5 days are added is obtained using the plusDays() 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.plusDays(5);
System.out.println("The Period after adding 5 days is: " + p2);
