import java.util.Scanner;

public class Week {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        for (int i = 0; i < 3; i++) {
            System.out.print("请输入一个数字：");
            int n= scan.nextInt();
            switch (n){
                case 0:
                    System.out.println("星期一"); break;
                case 1:
                    System.out.println("星期二"); break;
                case 2:
                    System.out.println("星期三"); break;
                case 3:
                    System.out.println("星期四"); break;

                    System.out.println("星期六"); break;
                case 6:
                    System.out.println("星期日"); break;
                default:
                    System.out.println("错误");break;
            }
