    Lightbulb Shopping cart help with code

    Hello, i need to get this shopping cart to work and i need help at creating a place to save the data after the "Enter product move".
    This is the code so far. I need this step to move on with delete, update, search
    Thanks in advance!

    import java.util.Scanner;

    public class Shoppingcart {

    private static Scanner scanner = new Scanner(System.in);
    private static String[] menuItems
    = { "Exit", "Insert Item", "Update Item", "Search Item", "Delete Item"

    private static Products productList;
    private static String item;

    static void printMenu() {
    int i = 0;
    for (String item : menuItems) {
    System.out.printf("%d -> %s\n", i, item);

    static int requestAction() {
    int choice = 0;
    do {
    System.out.print("Choose a number from the menu: ");
    if (scanner.hasNextInt())
    choice = scanner.nextInt();
    scanner.nextLine(); //
    } while (choice < 0 || choice >= menuItems.length);
    return choice;

    public static void main (String[] args){
    int test;
    do {
    test = requestAction();
    } while (test != 0);
    System.out.println("Exit from the app"); //

    private static void commander(int n) {
    switch (n) {
    case 1: insertItem();
    // case 2: updateitem();
    // break;
    // case 3: searchitem();
    // break;
    // case 4: deleteitem();


    static void insertItem() {
    System.out.print("Enter product: ");
    String item = scanner.nextLine();

    public class Products {
    private String[] [] items = new String[50][1];
    private int nextAvail = 0;

    public void insertItem(String[] item) {
    items[nextAvail] = item;

    public boolean isFull() {
    return (nextAvail >= items.length);

    public int findProduct(String item) {
    Object[] products = null;
    int nextAvail = 0;
    for (int i = 0; i < nextAvail; i++)
    if (products[i].equals(item) )
    return i;
    return -1;

    Default Re: Shopping cart help with code

    need help at creating a place to save the data
    Would a simple text file work to save the data between program executions?

    The code needs some comments describing what it is doing and how it is going to do it.

    Please edit your post and wrap your code with code tags:


    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
