Period negated() method in Java

An immutable copy of a Period where all the Period elements are negated can be obtained using the method negated() in the Period class in Java. This method requires no parameters and it returns the Period elements after negating them.

A program that demonstrates this is given as follows

Example

 Live Demo

import java.time.Period;
import java.time.LocalDate;
public class Demo {
   public static void main(String[] args) {
      String period = "P5Y7M15D";
      Period p = Period.parse(period);
      System.out.println("The Period is: " + p);
      System.out.println("The Period with elements negated is: " + p.negated());
   }
}

Output

The Period is: P5Y7M15D
The Period with elements negated is: P-5Y-7M-15D

Now let us understand the above program.

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

String period = "P5Y7M15D";
Period p = Period.parse(period);
System.out.println("The Period is: " + p);
System.out.println("The Period with elements negated is: " + p.negated());
