ZoneOffsetTransition hashCode() method in Java with Example

The hashCode() method of java.time.zone.ZoneOffsetTransition class is used to get the hash code for the zone offset transition object.

Syntax:

public int hashCode()

Parameter: This method does not accept any parameter.

Return Value: This method returns the hash code for the zone offset transition object.

Below are the examples to illustrate the hashCode() method:

Example 1:

// Java program to demonstrate
// hashcode() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.zone.*;

public class GFG {
    public static void main(String[] argv)
    {

        // creating and initializing
        // the object of LocalDateTime
        LocalDateTime loc
            = LocalDateTime.of(
                1999, 04, 25,
                03, 24, 45, 0);

        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off1
            = ZoneOffset.ofTotalSeconds(8);

        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off2
            = ZoneOffset.ofTotalSeconds(12);

        // creating and initializing
        // ZoneOffsetTransition Object
        ZoneOffsetTransition zonetrans1
            = ZoneOffsetTransition.of(
                loc, off1, off2);

        // getting the hash code for this object
        // by using hashcode() method
        int hash = zonetrans1.hashCode();

        // display the result
        System.out.println("hashcode : " + hash);
    }
}

Output:

hashcode : 1396559933

Example 2:

public class GFG {

    {

        // creating and initializing
        // the object of LocalDateTime
        LocalDateTime loc
            = LocalDateTime.of(
                2010, 04, 25,
                03, 56, 45, 0);

        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off1
            = ZoneOffset.ofTotalSeconds(8);

        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off2
            = ZoneOffset.ofTotalSeconds(12);

        // creating and initializing
        // ZoneOffsetTransition Object
        ZoneOffsetTransition zonetrans1
            = ZoneOffsetTransition.of(
                loc, off1, off2);

        // getting the hash code for this object
        // by using hashcode() method
        int hash = zonetrans1.hashCode();

        // display the result
        System.out.println("hashcode : " + hash);
    }
}

Output:

hashcode : 1539866618
