// Program to illustrate the isBefore() method 
  
import java.util.*; 
import java.time.*; 
import java.time.chrono.*; 
  
public class GfG { 
    public static void main(String[] args) 
    { 
        // Parses the first date 
        ChronoLocalDate dt1 
            = LocalDate.parse("2018-11-27");

        ChronoLocalDate dt2 
            = LocalDate.parse("2017-11-27");

        // is before this date 
        System.out.println(dt1.isBefore(dt2)); 
    } 
} 

Output:

false

Program 2:

// Program to illustrate the isBefore() method 
  
import java.util.*; 
import java.time.*; 
import java.time.chrono.*; 
  
public class GfG { 
    public static void main(String[] args) 
    { 
        // Parses the first date 
        ChronoLocalDate dt1

            = LocalDate.parse("2019-11-27"); 
  
        // Check if the specified date 
        // is before this date 
        System.out.println(dt1.isBefore(dt2)); 
    } 
}
