Java 我需要RPG类型清单的帮助。。。（爪哇）

在你投反对票之前，我甚至不知道该怎么做

如何创建一个.java或类，以便在执行过程中向其中添加来自不同类的文本以存储信息

从技术上讲，我试图实现的是一个基于文本的RPG的清单系统，它可以说，“嘿，你有一把剑！”并且“剑”出现在清单中。你可以输入“库存”，看到“你有一把剑”。它不能是println，因为我需要玩家能够随时访问它

我在网上搜索过，什么也没找到。 我如何进一步进行

下面的代码将显示我当前的库存系统，以及需要修复的原因：

    import java.util.Scanner;

    public class Class
    {

    public static void main(String[] args)
    {
        String choice;
        Scanner scan = new Scanner(System.in);
        System.out.println("COPYRIGHT 2016 HARBNGER STUDIOS\nTYPE AN 'option' TO GO TO THAT LOCATION\n\nSTART: You awake in a broken-down alabaster\nhouse with no knowledge of who\nyou are or where you came from.

        choice = scan.nextLine();{

            if(choice.equals("NORTH")){
            System.out.println("\n\n\n\n--TERMINAL_LOG--                JAN 16, 2644\n\nI FOUND THIS HANDHELD TERMINAL LOG. FIGURED I'D\nPUT IT TO SOME USE.\n\nI TRAVELED NORTH TO A RUN-DOWN VILLAGE.

请注意“清单1”和“清单3”

一旦玩家掌握了我的方法，如果他们知道库存数量，他们就可以用最好的武器和盔甲跳过游戏

谢谢你的帮助。我很感激。

对不起，这个问题似乎太模糊/太宽泛了。如果你被卡住了，你可以自己尝试一下，问一个特定的问题。@Manu我想我把范围缩小了一点……你可能想从学习面向对象编程开始。然后构建fitting类，比如具有“name”等属性的类“Item”，然后创建具有“add（Item）”等方法的背包类。如果我没有告诉你一些新的东西，请提前道歉，但你听起来像是一个还没有学会如何在课堂上工作的人。顺便说一句，main包含太多太具体的代码。使用一些存储地图的结构，并将代码划分为简单的单元，您可以轻松地监视这些单元。
