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
