用Java编写程序，要求输入1~7的某个数，输出表示一星期中相应的某一天的 单词：Monday、Tuesday等，用switch语句实现。

可以回答这个问题。以下是Java代码：

import java.util.Scanner;

public class Weekday {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.print("请输入1~7的某个数：");
        int day = input.nextInt();
        String weekday;
        switch (day) {
            case 1:
                weekday = "Monday";
                break;
            case 2:
                weekday = "Tuesday";
                break;
            case 3:
                weekday = "Wednesday";
                break;
            case 4:
                weekday = "Thursday";
                break;
            case 5:
                weekday = "Friday";
                break;
            case 6:
                weekday = "Saturday";
                break;
            case 7:
                weekday = "Sunday";
                break;
            default:
                weekday = "输入错误";
                break;
        }
        System.out.println("星期" + day + "是" + weekday);
    }
}
