如何在声明时将项目添加到哈希表？ [复制]

Question

所以我正在尝试创建一个基于文本的冒险/地牢爬行游戏。我正在尝试使用与我在基于文本的 Pokemon 游戏中使用的系统类似的系统来存储物品、怪物等。这是我在 C# 中用于存储系统的功能代码。

public static Dictionary<string, pokemonTrainer> pokemonTrainers = new Dictionary<string, pokemonTrainer>()
        {
            {"Robert", new pokemonTrainer{name="Robert",typesOfPokemon={"Plant","Normal"}, levelMultiplier=0.4}},
            {"James", new pokemonTrainer{name="James",typesOfPokemon={"Plant","Normal","Water","Fire","Ice","Flying","Electric","Poison","Psychic","Fighting","Dark","Dragon","Fairy","Rock","Ghost","Ground","Bug"},levelMultiplier=0.8}}
        };

我想创建我的哈希表，其中包含某些键值对，就像在 C# 代码中所做的那样，而不是仅仅使用 .put() 添加它们，这可能吗？如果是这样，我会怎么做？如果不是，那么创建这样一个存储系统的最佳方法是什么？

如果它有帮助，这是我在 java 中对哈希表的声明，

public static Hashtable<Integer, monster> monster_data_base = new Hashtable<Integer, monster>()
    {
        
    };

这是我想成为键值对的值部分的怪物类。

class monster
    {
        private int health;
        private int damage;
        private String name;
        private int level;
        monster(int health, int damage, String name, int level)
        {
            this.health=health;
            this.damage=damage;
            this.name=name;
            this.level=level;
        }
        String get_name() 
        {
            return name;
        }
        int get_health() 
        {
            return health;
        }
        int get_damage() 
        {
            return damage;
        }
        void change_health(int change_in_durabilty) 
        {
            health=health+change_in_durabilty;
        }
        int get_level() 
        {
            return level;
        }
    }

创建一个静态方法来初始化您的静态哈希表对象。这将在加载类时初始化。

public class Main {
    public static Hashtable<Integer,String> mytable = new Hashtable<>();
    
    static {
        initializeMytable();
    }

    // static initializer where you can initiate your static object
    static void initializeMytable() {
        mytable.put(2,"sam");
    }
    
    public static void main(String[] args) {
 
        // use your table where you need it later
        System.out.println(mytable);
    }
}
