Question

1. Read and understand the pseudocode of problem R2.19 in java from the end of chapter 2 in your textbook. In a Java class named WeekDays, write a java program that reads an input int between (0-6), and displays the corresponding day for that given input as below:

Enter a number (0-6): 2

** 2 is Tue **

！！！ NO if-else conditions

Answer 1

import java.util.Scanner;

public class WeekDays {
    public static void main(String[] args) {
        int n;
        Scanner scan = new Scanner(System.in);
        System.out.print("Enter a number (0-6): ");
        n = scan.nextInt();

        switch (n){
            case 0:
                System.out.println("** 0 is Sum **");
                break;
            case 1:
                System.out.println("** 1 is Mon **");
                break;
            case 2:
                System.out.println("** 2 is Tue **");
                break;
            case 3:
                System.out.println("** 3 is Wed **");
                break;
            case 4:
                System.out.println("** 4 is Thur **");
                break;
            case 5:
                System.out.println("** 5 is Fri **");
                break;
            case 6:
                System.out.println("** 6 is Sat **");
                break;
            default:
                System.out.println("Invalid input");
        }
    }
}
