The compareTo() method of ChronoLocalDate interface in Java method compares this date to another date.
Syntax:
public int compareTo(ChronoLocalDate other)
Parameter: This method accepts a parameter other which specifies the other date to compare to and it is not specifically null.
Return Value: It returns the comparator value which is negative if it is less else it is positive if it is greater.
Below programs illustrate the compareTo() method of ChronoLocalDate in Java:
Program 1:
// Program to illustrate the compareTo() method import java.util.*;import java.time.*;import java.time.chrono.*; public class GfG { public static void main(String[] args) { // First date ChronoLocalDate dt = LocalDate.parse("2018-11-01"); System.out.println(dt); // Second date ChronoLocalDate dt1 = LocalDate.parse("2018-11-14"); System.out.println(dt1); // Compare both dates System.out.println(dt1.compareTo(dt)); }} |
Output:
2018-11-01 2018-11-14 13
Program 2:
// Program to illustrate the compareTo() method import java.util.*;import java.time.*;import java.time.chrono.*; public class GfG { public static void main(String[] args) { // First date ChronoLocalDate dt = LocalDate.parse("2018-11-21"); System.out.println(dt); // Second date ChronoLocalDate dt1 = LocalDate.parse("2018-11-14"); System.out.println(dt1); // Compare both dates System.out.println(dt1.compareTo(dt)); }} |
Output:
2018-11-21 2018-11-14 -7
