以下是我的程序,当我输入相关的月份、日期和年份时,它返回错误的日期名称.

Below is my program and it is returning the wrong day name when I enter the related month, date and year.

我在这里缺少什么?

我的计划

import java.util.Calendar;
import java.util.Locale;
import java.util.Scanner;

public class TimeTest {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        String month = in.next();
        String day = in.next();
        String year = in.next();

        System.out.println(getDay(day, month, year));
    }

    private static String getDay(String day, String month, String year) {
        Calendar calendar = Calendar.getInstance();
        calendar.set(Integer.parseInt(year), Integer.parseInt(month), Integer.parseInt(day));
        return calendar.getDisplayName(Calendar.DAY_OF_WEEK, Calendar.LONG, Locale.getDefault());

    }
}      


输出:

09
24
2018
Wednesday       

它应该返回星期一",因为那是当天.

It should be returning "Monday", as that is the current day.

推荐答案

假设它是 9 月,但实际上在Calendar 类的术语是 August,因为 Calendar 类中月份从 00(Jan)、01(Feb)... 等开始.

You are passing 09 as Month assuming it's September but actually in term of Calendar class it's August because months start from 00(Jan), 01(Feb)... and so on in Calendar Class.

因此,为了获得正确的输出,您需要通过

Hence in order to the get correct output you need to pass

08 // September Month not August
24
2018

这是您的运行代码
