OffsetDateTime compareTo() method in Java with examples

The compareTo() method of OffsetDateTime class in Java compares this date-time to another date-time.
Syntax :  
public int compareTo(OffsetDateTime other)
Parameter : This method accepts a single parameter other which specifies the other date-time to compare to, not null.
Return Value: It returns the comparator value, negative if less, positive if greater.
Below programs illustrate the compareTo() method:
Program 1 : 
Java
// Java program to demonstrate the compareTo() methodimport java.time.OffsetDateTime;import java.time.ZonedDateTime;public class GFG {    public static void main(String[] args)    {        // Parses the date1        OffsetDateTime date1 = OffsetDateTime.parse("2018-12-12T13:30:30+05:00");        // Parses the date2        OffsetDateTime date2 = OffsetDateTime.parse("2018-12-12T13:30:30+05:00");        // Prints both dates        System.out.println("Date1: " + date1);        System.out.println("Date2: " + date2);        // Compare both        System.out.println("On comparing we get " + date1.compareTo(date2));    }} | 
Output
Date1: 2018-12-12T13:30:30+05:00 Date2: 2018-12-12T13:30:30+05:00 On comparing we get 0
Program 2 :
Java
// Java program to demonstrate the compareTo() methodimport java.time.OffsetDateTime;import java.time.ZonedDateTime;public class GFG {    public static void main(String[] args)    {        // Parses the date1        OffsetDateTime date1 = OffsetDateTime.parse("2018-12-12T13:30:30+05:00");        // Parses the date2        OffsetDateTime date2 = OffsetDateTime.parse("2015-12-12T13:30:30+05:00");        // Prints both dates        System.out.println("Date1: " + date1);        System.out.println("Date2: " + date2);        // Compare both        System.out.println("On comparing we get " + date1.compareTo(date2));    }} | 
Output
Date1: 2018-12-12T13:30:30+05:00 Date2: 2015-12-12T13:30:30+05:00 On comparing we get 3
Program 3 :
Java
// Java program to demonstrate the compareTo() methodimport java.time.OffsetDateTime;import java.time.ZonedDateTime;public class GFG {    public static void main(String[] args)    {        // Parses the date1        OffsetDateTime date1 = OffsetDateTime.parse("2013-12-12T13:30:30+05:00");        // Parses the date2        OffsetDateTime date2 = OffsetDateTime.parse("2015-12-12T13:30:30+05:00");        // Prints both dates        System.out.println("Date1: " + date1);        System.out.println("Date2: " + date2);        // Compare both        System.out.println("On comparing we get " + date1.compareTo(date2));    }} | 
Output
Date1: 2013-12-12T13:30:30+05:00 Date2: 2015-12-12T13:30:30+05:00 On comparing we get -2
