所以我想把这个游戏放到类和方法中。因此，带有类的不同页面并将主要方法保留在一个页面上。我不知道该怎么做，整个游戏都是我自己做的。如果有人可以帮助我，将不胜感激。基本上，我需要帮助进行类设计和继承（父子类）。还有方法块，如gameStart（）。
这是我的游戏：

public static void main (String[] args){
// System Objects

String[] enemies = {"Skeleton", "Zombie", "Warrior", "Assassin"};
int maxEnemyHealth = 75;
int enemyAttackDamage = 25;
// Player Variables
int health = 100; // How much health we have
int attackDamage = 50; // How much damage our player can do
int numHealthPotions = 3; // Number of health pots our player is set with
int healthPotionHealAmount = 30; // Amount a health the pot will raise
int healthPotionDropChance = 50; // Percentage drop
boolean running = true;
System.out.println("Welcome to the Dungeon Game!"); //Welcome Message

这就是你如何根据OOP（面向对象编程）的思想将你的游戏划分为几个类。您应该为游戏的每个实体设置类。我把它分成几类：
- 地下城游戏（拥有主要功能并充当主游戏控制器）
- 选手
- 敌人
- 游戏角色（摘要）
GameCharacter 类是玩家和敌人对象的父类，因为它们共享属性和方法（例如 health、attackDamage、attack（）、takeDamage（）...）
DungeonGame类具有主游戏循环，它与您编写的内容基本相同。唯一的变化是您希望玩家和/或敌人采取一些行动的点。现在，您不是直接在循环中调整所有变量，而是在玩家和敌人对象上调用各自的函数 - 例如 attack（）， takeDamage（） -和对象调整自己的变量。
这是面向对象编程的基本思想。另请注意，例如，只有玩家和敌方对象知道自己的当前生命值，因此每次游戏控制器想要打印玩家生命值时，它都必须通过调用 getter 函数来"请求"它。您还可以将运行状况的打印放入 Player 类中，如果打印消息始终相同......
这只是您如何进行游戏结构的一个例子 - 您仍然可以根据自己的喜好更改很多内容。再举一个例子，您可以将 Enemy 类本身转换为另一个抽象类，并为每种类型的敌人创建一个类。通过这种方式，你可以为每种敌人类型分配特殊能力。
