ChronoPeriod toString() method in Java with Examples

The toString() method of ChronoPeriod interface in Java is used to return a String representation of this ChronoPeriod.

Syntax:

ChronoPeriod toString()

Parameters: This method does not accepts any parameter.

Return Value: This method returns String representation of this

Below program illustrates the above method:

Program 1:

// Java code to show the toString() function

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

public class ChronoPeriodClass {

    // Function to negate given periods
    static void printString(ChronoPeriod p1)
    {

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

    // 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);

        printString(p1);
    }
}

Output:

P4Y11M10D

Program 2:

// Java code to show the toString() function

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

public class ChronoPeriodClass {

    // Function to negate given periods
    static void printString(ChronoPeriod p1)
    {

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

    // 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);

        printString(p1);
    }
}

Output:

P-4Y-11M-10D
