原文:https://www . geesforgeks . org/month day-is after-method-in-Java-with-examples/

isAfter() 方法的月日类用来检查这个月日是否在作为参数传递的月日之后。此方法返回一个显示相同内容的布尔值。

语法:

public boolean isAfter(MonthDay other)

参数:此方法接受一个参数另一个参数,即要比较的另一个月日。

返回值:如果这个月日在指定的月日之后,这个方法返回真,否则返回假。

下面的程序说明了 isAfter()方法: 程序 1:

// Java program to demonstrate
// MonthDay.isAfter() 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 isAfter() method
        boolean value = month.isAfter(othermonth);

        // print instance
        System.out.println("monthday:"
                           + month + " is after monthday:"
                           + othermonth + " = "
                           + value);
    }
}

Output:

monthday:--10-12 is after monthday:--11-12 = false

程序 2:

// Java program to demonstrate
// MonthDay.isAfter() 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 isAfter() method
        boolean value = month.isAfter(othermonth);

        // print instance
        System.out.println("monthday:"
                           + month + " is after monthday:"
                           + othermonth + " = "
                           + value);
    }
}

Output:

monthday:--10-12 is after monthday:--09-12 = true
