    }

My problem is here. I need to display the pizzas that the user has ordered along with the amount of pizzas ordered and I’m stuck here. there are no errors in the code it just doesnt display the following

    for(int i=1;i<orderDisplay.length;i++){
      if(orderDisplay[i]>0){
        System.out.println("       " + orderDisplay[i] +  " " + pizzaType[i] + " pizzas");
      }
    }
    System.out.println("The total amount of your order is " + formatMoney(totalA));
  }


  public static int readInt(String prompt){
    System.out.println(prompt);
    java.util.Scanner keyboard = new java.util.Scanner(System.in);                                
    return keyboard.nextInt();
  }
  public static String readString (String prompt){
    System.out.println (prompt);
    java.util.Scanner keyboard= new java.util.Scanner(System.in);
    return keyboard.nextLine();
  }

  public static String formatMoney(double phoneNum){
    java.text.NumberFormat  fmt = java.text.NumberFormat. getCurrencyInstance();
    return(fmt.format(phoneNum));
  }
}

Answer 1

You have set all the array elements of orderDisplay to 0.

int [] orderDisplay = {0,0,0,0,0,0,0,0,0,0,0,0,0};

U never changed the value of orderDispaly elements and checking for value greater than 0 and u have started your loop with value 1. check the below lines.

 for(int i=1;i<orderDisplay.length;i++){
      if(orderDisplay[i]>0){
        System.out.println("       " + orderDisplay[i] +  " " + pizzaType[i] + " pizzas");
      }
