Java随机选择

所以我一直在开发我的第一个Java游戏，它进展得很顺利，但我需要随机挑选一个int，然后把它们放在这里； 示例（不正确，只是我的想象）

。。。诸如此类

这就是我的看法，请注意，所有这些都可能是错误的。 这是实际代码

    package com.company;
import java.util.*;

public class Main {
    static Scanner scan = new Scanner(System.in);
    static Scanner rand = new Random();
    static dice die = new dice();
    public static String playerName;
    public static int Hp;
    public static int MaxHp;
    public static int EnmyHp;
    public static int Damage;
    public static int EnmyDamage;
    public static int EnmyClass;
    public static int Mana;
    public static int Level;
    private static void Stats() {
        if (EnmyClass.equals("Goblin")) {
            System.out.println(playerName + EnmyHp + Hp + Damage + EnmyDamage + Mana);
        } else {
            System.out.println(playerName + EnmyHp + Hp + Damage + EnmyDamage);
        }
    }
    private static void buildGoblin() {
        EnmyClass = "Goblin";
        EnmyHp = 10;
        EnmyDamage = 7;
        Level = 1;
        }
    private static void buildEnemy() {
        switch (Level) {
            case 1:
                MaxHp = 10;
                break;
            case 2:
                MaxHp = 20;
                break;
            case 3:
                MaxHp = 30;
                break;
    private static void encounter() 
        }
    }
}

java中的变量以小写开头，类以大写开头。现在就学会这一点，否则你（和其他人）会感到困惑

您可以将它们添加到数组中，然后从随机索引中选择一个

你可能想做的是为敌人或角色制作一个POJO，它拥有所有这些属性

你的问题是什么？@Jason我怎么能让它随机挑选一个敌人（我知道只有一个rn）谢谢你
