# Period minusYears() method in Java

Java 8Object Oriented ProgrammingProgramming

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

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.minusYears(3);
System.out.println("The Period after subtracting 3 years is: " + p2);
}
}

## Output

The Period is: P5Y7M15D
The Period after subtracting 3 years is: P2Y7M15D

Now let us understand the above program.

First the current Period is displayed. Then an immutable copy of the Period where 3 years are subtracted is obtained using the minusYears() 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.minusYears(3);
System.out.println("The Period after subtracting 3 years is: " + p2);
