The compareTo() method of OffsetTime class in Java compares this time to another time and returns zero if they are equal or a positive or negative integer depending on the comparison result.
Syntax:
public int compareTo(OffsetTime other)
Parameter: This method accepts a single mandatory parameter other which specifies the other time which will be compared with.
Return Value: It returns the comparator value. It returns a negative value if the other date is less or a positive value if greater.
Exceptions: The function throws NullPointerException if the other date which is passed is null.
Below programs illustrate the compareTo() method:
Program 1 :
// Java program to demonstrate the compareTo() method import java.time.OffsetTime; public class GFG { public static void main(String[] args) { // Parses the time OffsetTime time1 = OffsetTime.parse( "15:30:30+07:00" ); // Parses the time OffsetTime time2 = OffsetTime.parse( "15:30:30+07:00" ); // gets the offset time1 System.out.println( "time1: " + time1); // gets the offset time2 System.out.println( "time1: " + time2); System.out.println( "time1 when compared" + " to time2 returns: " + time1.compareTo(time2)); } } |
time1: 15:30:30+07:00 time1: 15:30:30+07:00 time1 when compared to time2 returns: 0
Program 2 :
// Java program to demonstrate the compareTo() method import java.time.OffsetTime; public class GFG { public static void main(String[] args) { // Parses the time OffsetTime time1 = OffsetTime.parse( "15:30:30+07:00" ); // Parses the time OffsetTime time2 = OffsetTime.parse( "12:10:30+07:00" ); // gets the offset time1 System.out.println( "time1: " + time1); // gets the offset time2 System.out.println( "time1: " + time2); System.out.println( "time1 when compared" + " to time2 returns: " + time1.compareTo(time2)); } } |
time1: 15:30:30+07:00 time1: 12:10:30+07:00 time1 when compared to time2 returns: 1
Program 3: :
// Java program to demonstrate the compareTo() method import java.time.OffsetTime; public class GFG { public static void main(String[] args) { // Parses the time OffsetTime time1 = OffsetTime.parse( "15:30:30+07:00" ); // Parses the time OffsetTime time2 = OffsetTime.parse( "17:10:30+07:00" ); // gets the offset time1 System.out.println( "time1: " + time1); // gets the offset time2 System.out.println( "time1: " + time2); System.out.println( "time1 when compared" + " to time2 returns: " + time1.compareTo(time2)); } } |
time1: 15:30:30+07:00 time1: 17:10:30+07:00 time1 when compared to time2 returns: -1
