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);
