Return Value: This method returns a new instance of Period after negating each element of the period.

Exceptions: It throws an ArithmeticException. This exception is caught if numeric overflow occurs.



Below program illustrates the above method:

Program 1:




// Java code to show the function to negate all
// elements of the period
import java.time.Period;
import java.time.temporal.ChronoUnit;
  
public class PeriodClass {
  
    // Function to negate given periods
    static void toNegate(Period p1)
    {
  
        System.out.println(p1.negated());
    }
  
    // Driver Code
    public static void main(String[] args)
    {
        // Defining period
        int year = 4;
        int months = 11;
        int days = 10;
        Period p1 = Period.of(year, months, days);
  
        toNegate(p1);
    }
}
Output:
P-4Y-11M-10D

Program 2:




// Java code to show the function to negate all
// elements of the period
import java.time.Period;
import java.time.temporal.ChronoUnit;
  
public class PeriodClass {
  
    // Function to negate given periods
    static void toNegate(Period p1)
    {
  
        System.out.println(p1.negated());
    }
  
    // Driver Code
    public static void main(String[] args)
    {
        // Defining period
        int year = -4;
        int months = -11;
        int days = -10;
        Period p1 = Period.of(year, months, days);
  
        toNegate(p1);
    }
}
Output:
