Below programs illustrate the isBefore() method:
Program 1:

// Java program to demonstrate
// MonthDay.isBefore() method
  
import java.time.*;
  
public class GFG {
    public static void main(String[] args)
    {
        // create a MonthDay object
        MonthDay month = MonthDay.parse("--10-12");
  
        // create other MonthDay object
        MonthDay othermonth = MonthDay.parse("--11-12");
  
        // apply isBefore() method
        boolean value = month.isBefore(othermonth);
  
        // print instance
        System.out.println("monthday:"
                           + month + " is before monthday:"
                           + othermonth + " = "
                           + value);
    }
}

Output:

monthday:--10-12 is before monthday:--11-12 = true

Program 2:

// Java program to demonstrate
// MonthDay.isBefore() method
  
import java.time.*;
  
public class GFG {
    public static void main(String[] args)
    {
        // create a MonthDay object
        MonthDay month = MonthDay.parse("--10-12");
  
        // create other MonthDay object
        MonthDay othermonth = MonthDay.parse("--09-12");
  
        // apply isBefore() method
        boolean value = month.isBefore(othermonth);
  
        // print instance
        System.out.println("monthday:"
                           + month + " is before monthday:"
                           + othermonth + " = "
                           + value);
    }
}

Output:

monthday:--10-12 is before monthday:--09-12 = false
