Java方法生成通过实例变量传递的随机数

Question

我正在用 Java 制作一个基于文本的游戏，我正在使用类和实例变量，并且我正在尝试创建一个方法，该方法根据实例变量 max_attack有。

public class badPlayer 
{
    String description;
    int health;
    int award;
    int max_attack;

    public badPlayer(String description, int health, int award, int attack){            
        this.description=description;
        this.health = health;
        this.award = award;
        this.max_attack = attack;
    }

   Random rnd = new Random();

    public int maxAttack(){ 
        int rand_int1 = rnd.nextInt(max_attack);
        return rand_int1;   
    }   
}

public class troll extends badPlayer
{
    troll(int attack){
        super("troll", 100, 50, 100);
    } 
}

输出

troll1005089

我想要创建 1 到 100 之间的随机数的方法。

Answer 1

Random r = new Random();
int low = 1;
int high = 100;
int result = r.nextInt(high-low) + low;
