LocalDate Class isBefore() method

• isBefore() method is available in java.time package.
• isBefore() method is used to check whether this LocalDate value comes before the given ChronoLocalDate (l_date) or not.
• isBefore() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• isBefore() method does not throw an exception at the time of checking the status.

Syntax:

    public boolean isBefore(ChronoLocalDate l_date);

Parameter(s):

• ChronoLocalDate l_date – represents the ChronoLocalDate object to be compared with this LocalDate.

Return value:

The return type of this method is boolean, it returns true when this LocalDate value comes before the given ChronoLocalDate value otherwise it returns false.

Example:

// Java program to demonstrate the example 
// of isBefore(ChronoLocalDate l_date) method 
// of LocalDate

import java.time.*;

public class IsBeforeOfLocalDate {
    public static void main(String args[]) {
        // Instantiates two LocalDate
        LocalDate l_da1 = LocalDate.parse("2007-04-04");
        LocalDate l_da2 = LocalDate.now();

        // Display l_da1,l_da2
        System.out.println("LocalDate l_da1 and l_da2: ");
        System.out.println("l_da1: " + l_da1);
        System.out.println("l_da2: " + l_da2);

        System.out.println();

        // Here, this method checks whether this
        // date l_da1 comes before the given date 
        // l_da2 or not i.e. here it returns
        // true because l_da1 comes before
        // the given date l_da2
        boolean status = l_da1.isBefore(l_da2);

        // Display status
        System.out.println("l_da1.isBefore(l_da2): " + status);

        // Here, this method checks whether this 
        // date l_da2 comes before the given date 
        // l_da1 or not i.e. here it returns
        // false because l_da2 comes after
        // the given date l_da1
        status = l_da2.isBefore(l_da1);

        // Display status
        System.out.println("l_da2.isBefore(l_da1): " + status);
    }
}

Output

LocalDate l_da1 and l_da2: 
l_da1: 2007-04-04
l_da2: 2020-05-30

l_da1.isBefore(l_da2): true
l_da2.isBefore(l_da1): false
