课堂练习–玩家对战，击败掉装备，随机暴击率
实体类如下：

package cn.hp;

/*
 * 玩家类
 * 属性：名字、类型、生命值、防御值、攻击力
 * 方法：自我介绍、pk
 * */

    private  int attack;
    private int crit;

    //随机暴击率

    public String getName() {

    }

    public void setName(String name) {
        this.name = name;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public int getLife() {
        return life;
    }

    public void setLife(int life) {
        this.life = life;
    }

    public int getDefence() {
        return defence;
    }

    public void setDefence(int defence) {
        this.defence = defence;
    }

    public int getAttack() {
        return attack;
    }

    public void setAttack(int attack) {
        this.attack = attack;
    }

    //构造器：如果定义了一个有参的构造器，一定要构造无参构造器
    public Player(String name, String type, int life, int defence, int attack) {
        this.name = name;
        this.type = type;
        this.life = life;
        this.defence = defence;
        this.attack = attack;
    }

    public Player() {
    }
}

实现类如下：

package cn.hp;

/**
 * 创建玩家进行对战
 */
public class PlayTest {
    public static void main(String[] args) {
        Player p1 = new Player("王日天","狂战士",1500,80,320);
        Player p2 = new Player("赵穹弯","法师",1000,40,450);
        p2.pk(p1);
    }
}
