The negated() method of Period class in Java is used to return a new instance of Period after negating all the elements of the period YEAR, MONTH, DAY.
Syntax:
public Period negated()
Parameters: This method does not accepts any parameter.
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 periodimport 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 periodimport 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:
P4Y11M10D
