Shopping list error

Question

I need a bit help how to fill in these methods. Any help would be appreciated guys.

package week9;

import java.util.ArrayList;
import java.util.Scanner;

public class ShoppingList1 {

public static void main(String[] args) {

Scanner sIn = new Scanner(System.in);
ArrayList<String> shoppingList = new ArrayList<String>();
String choice;
boolean done = false;

do {
// Print out the menu to the console
System.out.println();
System.out.println("1. Add Items");
System.out.println("2. Delete Items");
System.out.println("3. Show Items");
System.out.println("4. Sort Items");
System.out.println("5. Exit");
System.out.print("Please enter a command: ");
choice = sIn.nextLine();

switch (choice) {
case "1": // Add items to the Shopping List
System.out.println(addItems(sIn, shoppingList) + " items have been added to your Shopping List.");
break;
case "2": // Delete items from the Shopping List
System.out
.println(deleteItems(sIn, shoppingList) + " items have been deleted from your Shopping List.");
break;
case "3": // Show the items in the Shopping List
showItems(shoppingList);
break;
case "4": // Sort the items in the Shopping List
sortItems(shoppingList);
break;
case "5": // Exit the program
System.out.println();
System.out.println("Goodbye");
done = true;
break;
default: // Handles all input that is not between 1-5
System.out.println("Invalid response. Please enter a choice from the menu (1-5).");
} // End of switch (choice)
} while (!done); // Keep running the program until the user quits

sIn.close();
}// end of main()

public static int addItems(Scanner sIn, ArrayList<String> shoppingList) {

return 0;
}// end of method addItems(ArrayList<String>)

public static int deleteItems(Scanner sIn, ArrayList<String> shoppingList) {

return 0;
}// end of method deleteItems(ArrayList<String>)

public static

Please tag "java", not "javascript". Java and Javascript are different languages.

Please link your complete code. Please do not paste the code into the description.
– Go to Code section, click+, select the programming language, insert your code, save.
– Come back to this thread, click +, Insert Code, sort for My Code Bits, select your code.

Describe what the code is supposed to do.
