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
