Question

Use a switch statement to display "one" if the user has entered 1, "two" if the user has entered 2, and "three" if the user has entered 3. If a number other than 1, 2, or 3 is entered, the program should display an error message: "Enter one of the numbers - 1, 2, or 3."

Answer 1

Answer:

import java.util.Scanner;

public class num5 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter one the numbers - 1, 2, or 3.");

       int num = in.nextInt();

       switch (num){

           case 1:

               System.out.println("one");

               break;

           case 2:

               System.out.println("two");

               break;

           case 3:

               System.out.println("three");

               break;

           default:

               System.out.println("Error");

       }

   }

}

Explanation:

• Using Java Programming Language
• User Scanner Class to prompt, receive and store user's input
• Use a switch statement with three cases as required by the question to output one, two or three
• Use the default statement to handle any other case
