ChronoPeriod negated() method in Java with Examples
The negated() method of ChronoPeriod interface in Java is used to return a new instance of ChronoPeriod after negating all the elements of the period YEAR, MONTH, DAY.
Syntax:
ChronoPeriod negated()
Parameters: This method does not accepts any parameter.
Return Value: This method returns a new instance of ChronoPeriod 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.*; import java.time.chrono.*; import java.time.temporal.ChronoUnit; public class ChronoPeriodClass { // Function to negate given periods static void toNegate(ChronoPeriod 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 ; ChronoPeriod 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.*; import java.time.chrono.*; import java.time.temporal.ChronoUnit; public class ChronoPeriodClass { // Function to negate given periods static void toNegate(ChronoPeriod 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 ; ChronoPeriod p1 = Period.of(year, months, days); toNegate(p1); } } |
Output:
P4Y11M10D
