I'm developing a console program that allows you to build your own pizza. I'm getting unexpected output when I run my code. I'm expecting it to print the menu, accept user input for topping choice, ask if the user wants to continue adding toppings and repeat. However this is the output I'm getting.
No key was pressed between highlighted section
I suspected it has something to do with my last else statement:
else {System.out.println("You did not enter a valid topping choice");}
However removing that did not fix the issue.
Does anyone have any insight as to what is causing the menu to be printed twice after each selection?
Here is my code:
package com.mycompany.pizzapizza;

public class test {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
//variable for keeping track of how many toppings are selected

System.out.println("Build Your Own Pizza");
System.out.println("---------------------");
//selecting the crust
String crustType= "";
boolean status = true;
while(status) {
System.out.println("\nChoose your crust:");
System.out.println("type R for Regular | type C for Cauliflower");
crustType = sc.nextLine();
if (crustType.equalsIgnoreCase("R")) {
crustType = "Regular Crust";
maxToppings++;
status = false;
}
else if (crustType.equalsIgnoreCase("C")) {
crustType = "Cauliflower Crust";
maxToppings++;
status = false;
}
else {
System.out.println("Please enter a valid crust");
status = true;
}
}
System.out.println("\n***********************************************");
//selecting the sauce

boolean status1 = true;
while(status1) {
System.out.println("\nPlease Choose One Sauce Option");
System.out.println("Type Y for Red Sauce, or N for No Red Sauce.");
sauceType = sc.nextLine();
if (sauceType.equalsIgnoreCase("Y")) {
maxToppings++;
System.out.println("A. 1/4cup B. 1/2cup");
