Question

Requires:
variables, data types, and numerical operators
basic input/output
logic (if statements, switch statements)

Write a program that presents the user w/ a choice of your 5 favorite beverages (Coke, Water, Sprite, ... , Whatever).
Then allow the user to choose a beverage by entering a number 1-5.
Output which beverage they chose.

If you program uses if statements instead of a switch statement, modify it to use a switch statement.
If instead your program uses a switch statement, modify it to use if/else-if statements.

Modify the program so that if the user enters a choice other than 1-5 then it will output "Error. choice was not valid, here is your money back."

Explanation / Answer

Using switch

BeveragesMenu.java

import java.util.Scanner;

public class BeveragesMenu {

  
   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       System.out.println("Menu: 1. Coke 2. Water 3. Sprite 4. Fanta 5. Milk Enter your choice: ");
       int choice = scan.nextInt();
       switch(choice){
       case 1: System.out.println("You have choosen Coke");break;
       case 2: System.out.println("You have choosen Water");break;
       case 3: System.out.println("You have choosen Sprite");break;
       case 4: System.out.println("You have choosen Fanta");break;
       case 5: System.out.println("You have choosen Milk");break;
       default: System.out.println("Error. choice was not valid, here is your money back.");
       }

   }

}

Using ifelse

BeveragesMenu.java

import java.util.Scanner;

public class BeveragesMenu {

  
   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       System.out.println("Menu: 1. Coke 2. Water 3. Sprite 4. Fanta 5. Milk Enter your choice: ");
       int choice = scan.nextInt();
       if(choice== 1) {
           System.out.println("You have choosen Coke");
           }
       else if (choice == 2) {
           System.out.println("You have choosen Water");
       }
       else if (choice == 3) {
           System.out.println("You have choosen Sprite");
       }
       else if (choice == 4) {
           System.out.println("You have choosen Fanta");
       }
       else if (choice == 5) {
           System.out.println("You have choosen Milk");
       }
       else{
           System.out.println("Error. choice was not valid, here is your money back.");
       }
   }

}
