How can I put the item order in a different class?

OK, trying this now. Still not quite right....

The instructions were:

A class named orderEntry should also be created with the appropriate constructor, accessor and mutator methods. As the user is entering the items they wish to order, these items should be placed into a separate array as they are ordered. Once the user is done entering items, the program should use the array to output all items that were ordered to the screen, with their prices.

Not really subject of the question but don't write code like `quit != "done"`. For more info visit [How do I compare strings in Java?](https://stackoverflow.com/questions/513832/how-do-i-compare-strings-in-java) — Pshemo, Aug 06 '18 at 13:20
Anyway your question is unclear. What do you mean by placing "everything inside the while loop in a different class"? What does it have to do with instructions you gave us? What are you trying to achieve and what problems are you facing? — Pshemo, Aug 06 '18 at 13:23
I need to have the user entering the items within a different class. — dovakiin5574, Aug 06 '18 at 13:25
That's just it, I didn't put anything into another class yet — dovakiin5574, Aug 06 '18 at 13:29
I'm just not understanding the concept of accessing the data between classes I think — dovakiin5574, Aug 06 '18 at 13:49

This is not a solution i would recommend, but for the sake of learning how to use methods: just put it in another class and call the method from there. Give the methods the parameters needed.

public class whileMethod(String quit, double listTime, double listMax, Scanner input, double priceAdd, ArrayList<String> buyItemList, ) {

while (quit != "done" || listTime <= listMax)
     {

         System.out.println("Please enter item " + listTime + " :");
         itemEntry = input.nextInt();

         if (itemEntry == 1){
             priceAdd = spagPrice;
             buyitemList.add("Spaghetti Tacos");

         }
         else if (itemEntry == 2){
             priceAdd = ramenPrice;
             buyitemList.add("Ramen Pizza");
         }
         else if (itemEntry == 3){
             priceAdd = pepperPrice;
             buyitemList.add("Stuffed Bell Pepper");
         }
         else if (itemEntry == 4){
             priceAdd = steakPrice;
             buyitemList.add("Mushroom Steak");
         }
         else if (itemEntry == 5){
             priceAdd = tunaPrice;
             buyitemList.add("Tuna Suprise");
         }
         else {
             priceAdd = 0;

         }


         buyList.add((int) priceAdd);

         listTime += listTime;



     }

From here u can call the method in the class:

whileMethod(and all the attributtes needed)

System.out.println("Please enter a number to indicate your desired item. Type 'done' when you are done or enter up to 10 items."); System.out.println(" " + "1" + " " + " " + " " + "2" + " " + " " + " " + "3" + " " + " " + " " + "4" + " " + " " + " " + "5"); System.out.println(itemList); orderEntry (String quit, listTime, listMax, priceAdd, buyitemList); System.out.println("---------------------"); System.out.println("---------------------"); double subTotal = 0; double taxAmount = 0; Like this? — dovakiin5574, Aug 06 '18 at 13:35
