Question

How do I record every user Input and then display all of it in the scream. In my code i ask the user

for a series of food item, then i ask for the toppings. I need to display every input of food and toppings the

user enters. The output must look like this

Here is your order <name>

Appetizer: [ Wings, Blue cheese, Ranch ]

Main Course: [ Hamburger: mushrooms , Advocado ]

Dessert: [ Pie: Powder Sugar, Scoop of IceCream ]

This is my code:

import java.util.Scanner;
class Main {
static void display(String menu[]) {
for (int i = 0; i<menu.length; i++) {
System.out.println(i + " - " + menu[i]);
}
System.out.print("Enter the number for your selection: ");
}
public static void main(String[] args) {
int selection = 0;
int Appetizerselection = 0;
int MainCourseSelection = 0;
int DessertSelection = 0;
int AppetizerToppingsSelection = 0;
int MainCourseToppingsSelection = 0;
int DessertSelectionToppings = 0;
int i = 0;

String list = "";
String MainMenu[] = {"Nothing", "Appetizer", "Main Course", "Dessert"};
String Appetizer[] = {"Nothing", "Wings", "Salad", "Fries"};
String AppetizerToppings[] = {"Nothing", "Blue Cheese", "Ranch", "Cheese"};
String MainCourse[] = {"Nothing", "Steak", "Hamburger", "Pasta"};
String MainCourseToppings[] = {"Nothing", "Mushrooms", "Advocado", "Black Olives"};
String Dessert[] = {"Nothing", "Chocolate Cake", "Pie", "Cookies"};
String DessertToppings[] = {"Nothing", "Powder Sugar", "Scoope of IceCream", "Condense Milk"};


Scanner scan = new Scanner(System.in);
System.out.println("Welcome to the food festival");
  

while(true){
System.out.println("Would you like to place an order");
String input = scan.nextLine();
if (input.equalsIgnoreCase("Yes")) {
System.out.println("What is your name for the order?");
String name = scan.nextLine();





// @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@Main Menu@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
do {
System.out.println("Select from menu, " + name);
display(MainMenu);
selection = scan.nextInt();
if (selection > 0 && selection<MainMenu.length) {
System.out.println("Current String: " + selection);
}

////////////////////////////////////////////////Appetizer Menu//////////////////////////////////////////////////////////////////////

if (selection == 1) {
System.out.println("Appetizer Menu:");
do {
display(Appetizer);
Appetizerselection = scan.nextInt();


if (selection > 0 && selection<Appetizer.length) {

Appetizer[selection];


}
  

if (Appetizerselection > 0) {
System.out.println("Topping Menu:");
do {
display(AppetizerToppings);
AppetizerToppingsSelection = scan.nextInt();
if (AppetizerToppingsSelection > 0)

System.out.println("Current String: " + AppetizerToppings[AppetizerToppingsSelection]);
} while (AppetizerToppingsSelection != 0);
}
} while (Appetizerselection != 0);
}

//*************************************************** Main Course Menu*************************************************************
if (selection == 2) {
System.out.println("Main Course Menu:");
do {
display(MainCourse);
MainCourseSelection = scan.nextInt();
if (selection > 0 && selection<MainCourse.length) {
System.out.println("Current String: " + MainCourse[selection]);
}
if (MainCourseSelection > 0) {
System.out.println("Topping Menu:");
do {
display(MainCourseToppings);
MainCourseToppingsSelection = scan.nextInt();
if (MainCourseToppingsSelection > 0) System.out.println("Current String: " + MainCourseToppings[MainCourseToppingsSelection]);
} while (MainCourseToppingsSelection != 0);
}
} while (MainCourseSelection != 0);
}

//+++++++++++++++++++++++++++++++++++++++++++++++++++Dessert Menu++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
if (selection == 3) {
System.out.println("Dessert Menu");
do {
display(Dessert);
DessertSelection = scan.nextInt();
if (selection > 0 && selection<Dessert.length) {
System.out.println("Current String: " + Dessert[selection]);
}
if (DessertSelection > 0) {
System.out.println("Topping Menu");

} while (DessertSelection != 0);
}
//++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++


} while (selection != 0);


System.out.println( Appetizer[selection] );

System.out.println("Thank you for ordering come again");
break;


}


else if (input.equalsIgnoreCase("no")) {
System.out.println("Thank you for stopping by, maybe next time you'll sample our menu");
break;


}




}

hello student, you are most welcome here.
I am just giving you the most suitable and relatable answer please go through it and see how can we record any data at runtime using generic. I did not go or changes in your code because your idea is different and it very long code. But I have to give you here an idea for your problem.
For the record your data as like in your program you should use ArrayList in java because in your code you are proceeding at run time, therefore, the idea behind that to record all user activity used ArrayList.
Now let's see how ArrayList works and how to use it. I can not implement or change all of your code because i don't know why exactly you wrote your line and what is the reason behind it. I damm sure I must give you an idea which will guide you to get your whole working code.
if you like my work then please give me a thumb up. happy coding.

in your code there can maximum optimized suitable and easy way to solve this question. if you have any quarry then please ask in comment.

I am just gonna write a small program that will record all input(history) and display it.

here is some student they will enter their name and grade and we will record it and display it.

package arrayList;
import java.util.Scanner;
import java.util.ArrayList;

public class Student
{

public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
ArrayList<String> sName = new ArrayList<String>(); // just initializede an array list to record student name.
boolean test=true;
while (test)
{
System.out.println(" Enter Name");

sc.nextLine(); // it is for enter button for some JDK if you jdk is working correctly then disable it.

String s = sc.nextLine();

if(s.equals("N"))
{
break;
}
else
{
sName.add(s);
}

ArrayList<Double> grde = new ArrayList<Double>(); // just initializede an array list to record grade.
System.out.println("Enter grade");
// I am just taken dummy fore record in your problem you can make boundation to selected item length.
for (int j = 0; j < 4; j++)
{

Double g = sc.nextDouble();
grde.add(g);
}

// now let print all recorded your data.
System.out.println(sName);

System.out.println(" ");
System.out.print(grde);
}
}
}
