ChronoPeriod equals() method in Java with Examples

The equals() method of ChronoPeriod interface in Java is used to check if two given periods are equal or not.

The comparison is based on the type ChronoPeriod and each of the three years, months and date. To be equal, all of the three years, month and date must be individually equal.

Syntax:

boolean equals(ChronoPeriod secondChronoPeriod)

Parameters: This method accepts a single parameter secondChronoPeriod which is the another period to compare with.

Return Value: The above methods returns true if given periods are equal, else it returns false.

Below programs illustrate the above method:

Program 1:

// Java code to show the period
// equals for two given periods

import java.time.*;
import java.time.chrono.*;

public class ChronoPeriodClass {

    // Function to check if two given periods
    // are equals or not
    static boolean
    checkIfEqualChronoPeriod(ChronoPeriod firstChronoPeriod,
                             ChronoPeriod secondChronoPeriod)
    {

        return firstChronoPeriod.equals(secondChronoPeriod);
    }

    // Driver Code
    public static void main(String[] args)
    {

        // Given period
        ChronoPeriod first = Period.ofDays(28);
        ChronoPeriod second = Period.ofDays(8);

        System.out.println(
            checkIfEqualChronoPeriod(first, second));
    }
}

Output:

false

Program 2:

// Java code to show the period
// equals for two given periods

import java.time.*;
import java.time.chrono.*;

public class ChronoPeriodClass {

    // Function to check if two given periods
    // are equals or not
    static boolean
    checkIfEqualChronoPeriod(ChronoPeriod firstChronoPeriod,
                             ChronoPeriod secondChronoPeriod)
    {

        return firstChronoPeriod.equals(secondChronoPeriod);
    }

    // Driver Code
    public static void main(String[] args)
    {

        // Given period
        ChronoPeriod first2 = Period.ofDays(28);
        ChronoPeriod second2 = Period.ofDays(28);

        System.out.println(
            checkIfEqualChronoPeriod(first2, second2));
    }
}

Output:

true
