Question

I have tried the following code in many ways but it just doesn’t work. I have two problems with it.

1. I need it to not continue to QUANTITY when I press X.
2. If I want to continue, i.e., I do not press X but enter a code I should be pressing, it takes the first input correctly, however, when it goes around the loop the second type, it outputs something like “CODE: QUANTITY: ” on the same line.

I would really appreciate help here, because I am stuck and google’s been no help. I am completely new to programming, with no previous experience in any language, so I would really appreciate detailed help.

Here’s the code:

import java.util.Scanner;
class WHY
{
     public static void main(String[] args)
     {
          Scanner in = new Scanner(System.in);
          boolean count = true;

          for (int i = 0; count; i++)
          {
               System.out.print("CODE: (X to terminate)");
               String code = in.nextLine();
               System.out.print("QUANTITY: ");
               int quantity = in.nextInt();

               if (code.equals("X"))
                    count = false;
          }
     }    
}

Answer 1

    Scanner in = new Scanner(System.in);

    while (true) {
        System.out.print("CODE: (X to terminate)");
        String code = in.nextLine();
        if (code.equalsIgnoreCase("x")) {
            break;
        }

        System.out.print("QUANTITY: ");
        int quantity = in.nextInt();
        in.nextLine();
    }
