ZoneOffsetTransition compareTo() method in Java with Example

The compareTo() method of java.time.zone.ZoneOffsetTransition class is used to make comparison between two objects of ZoneOffsetTransition type. The comparison is made based on the instants of transition. 
Syntax:

public int compareTo(ZoneOffsetTransition transition)

Parameter: This method takes a transition of ZoneoffsetTransition type and compares it with this transition. 
Return Value: This method returns zero if both the objects of the ZoneOffsetTransition are equal, a negative value if the passed transition is less than this transition and a positive value if the passed transition is greater than this transition.
Below are the examples to illustrate the compareTo() method:
Example 1:

Java

// Java program to demonstrate
// compareTo() 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);

        // Creating and initializing
        // ZoneOffsetTransition Object
        ZoneOffsetTransition zonetrans2
            = ZoneOffsetTransition.of(
                loc, off1, off2);

        // Comparing both object using
        // compareTo() method
        int status
            = zonetrans1.compareTo(
                zonetrans2);

        // Display the result
        if (status == 0)
            System.out.println(
                "zonetrans1 is equal to zonetrans2");
        else if (status > 0)
            System.out.println(
                "zonetrans1 is greater than zonetrans2");
        else
            System.out.println(
                "zonetrans1 is lesser than zonetrans2");
    }
}

Output:

zonetrans1 is equal to zonetrans2

        // Creating and initializing the

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

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

        // Creating and initializing
        // ZoneOffsetTransition Object
        ZoneOffsetTransition zonetrans2
            = ZoneOffsetTransition.of(
                loc, off2, off1);

        // Comparing both object using
        // compareTo() method
        int status
            = zonetrans1.compareTo(
                zonetrans2);

        // Display the result
        if (status == 0)
            System.out.println(
                "zonetrans1 is equal to zonetrans2");
        else if (status > 0)
            System.out.println(
                "zonetrans1 is greater than zonetrans2");
        else
            System.out.println(
                "zonetrans1 is lesser than zonetrans2");
    }
}

Output:

zonetrans1 is greater than zonetrans2
