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 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:
P4Y11M10D
