// 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
程序 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:
