ZoneOffsetTransitionRule hashCode() method in Java with Example

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

Syntax:

public int hashCode()

Parameter: this method does not accept any parameter.

Return Value: This method returns the hash code of this zone offset transition rule 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
        // ZoneOffsetTransitionRule Object
        ZoneOffsetTransitionRule zonetrans1
            = ZoneOffsetTransitionRule
                  .of(
                      Month.JANUARY, 12,
                      DayOfWeek.SUNDAY,
                      LocalTime.of(03, 24, 45),
                      false,
                      ZoneOffsetTransitionRule
                          .TimeDefinition
                          .STANDARD,
                      ZoneOffset.ofTotalSeconds(8),
                      ZoneOffset.ofTotalSeconds(17),
                      ZoneOffset.ofTotalSeconds(12));

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

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

Output:

hash code : 402556303

                      ZoneOffsetTransitionRule
                          .TimeDefinition
                          .STANDARD,
                      ZoneOffset.ofTotalSeconds(8),
                      ZoneOffset.ofTotalSeconds(17),
                      ZoneOffset.ofTotalSeconds(12));

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

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

Output:

hash code : 756450703
