The compareTo() method of LocalDate class 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 LocalDate in Java:
Program 1:
// Program to illustrate the compareTo() method import java.util.*;
import java.time.*;
public class GfG {
public static void main(String[] args)
{
// First date
LocalDate dt = LocalDate.parse( "2018-11-01" );
System.out.println(dt);
// Second date
LocalDate 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.*;
public class GfG {
public static void main(String[] args)
{
// First date
LocalDate dt = LocalDate.parse( "2018-11-21" );
System.out.println(dt);
// Second date
LocalDate 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
