Question

In a file called NumbersToMonths.java, write a program that:

• Asks the user to specify a month as an integer between 1 and 12. It is OK for your program to crash when the user does not enter a valid integer.
• Prints out the name of the corresponding month.
• Prints out "This number does not correspond to a month." if the integer is less than 1 or greater than 12.

For example: if the user enters 1, your program output should look EXACTLY like this:

Please indicate a month as an integer from 1 to 12: 1
January

import java.util.Scanner;

public class NumbersToMonths {
    public static String getMonth(int num){
        switch (num){
            case 1:
                return "January";
            case 2:
                return "February";
            case 3:
                return "March";
            case 4:
                return "April";
            case 5:
                return "May";
            case 6:
                return "June";
            case 7:
                return "July";
            case 8:
                return "August";
            case 9:

            case 10:

            case 11:
                return "November";
            case 12:
                return "December";
            default:
                return "";
        }
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int n;
        System.out.print("Please indicate a month as an integer from 1 to 12: ");
        n = scanner.nextInt();
        String res = getMonth(n);
        if(res.equals("")){
            System.out.println("This number does not correspond to a month.");
        }
        else{
            System.out.println(res);
        }
    }
