ChronoPeriod negated() method in Java with Examples

Last Updated : 24 Jun, 2019
The normalized() method of ChronoPeriod interface in Java is used to return a new instance of ChronoPeriod after normalizing years and months. Syntax: 
ChronoPeriod normalized()
Parameters: This function does not accepts any parameter. Return Value: This function returns a new instance of ChronoPeriod after normalizing year and month 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 
// Java code to show the function to normalize
// months and years of the period

import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;

public class ChronoPeriodClass {

    // Function to normalize given periods
    static void toNormalize(ChronoPeriod p1)
    {

        System.out.println(p1.normalized());
    }

    // Driver Code
    public static void main(String[] args)
    {
        // Defining period
        int year = 4;
        int months = 15;
        int days = 10;
        ChronoPeriod p1 = Period.of(year, months, days);

        toNormalize(p1);
    }
}
Output: 
P5Y3M10D
Program 2: This will not normalize the number of days. Java 
// Java code to show the function to normalize
// months and years of the period

import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;

public class ChronoPeriodClass {

    // Function to normalize given periods
    static void toNormalize(ChronoPeriod p1)
    {

        System.out.println(p1.normalized());
    }

    // Driver Code
    public static void main(String[] args)
    {
        // Defining period
        int year = 10;
        int months = 25;
        int days = 366;
        ChronoPeriod p1 = Period.of(year, months, days);

        toNormalize(p1);
    }
}
Output: 
P12Y1M366D
