Java周总结4

1、进行面向对象的案例：

package com.myjava.playgame;

import java.util.Random;

public class user {

    //姓名。血量,性别，长相
    private String name;
    private int blool;
    private String gender;
    private String face;

    //长相数组
    String[] boyfaces = {"风流俊雅","气字轩昂", "相貌英俊", "五官端正", "相貌平平", "一塌糊涂", "面目狰狞"};
    String[] girlfaces = {"美奂绝伦", "沉鱼落雁", "婷婷玉立", "身材娇好", "相貌平平", "相貌简陋", "惨不忍睹"};

    //招式数组
    String[] attacks_desc = {
            "%s使出了一招【背心钉】，转到对方的身后，一掌向%s背心的灵台穴拍去。",
            "%s使出了一招【游空探爪】，飞起身形自半空中变掌为抓锁向%s。",
            "%s大喝一声，身形下伏，一招【劈雷坠地】，捶向%s双腿。",
            "%s运气于掌，一瞬间掌心变得血红，一式【掌心雷】，推向%s。",
            "%s阴手翻起阳手跟进，一招【没遮拦】，结结实实的捶向%s。",
            "%s上步抢身，招中套招，一招【劈挂连环】，连环攻向%s。"
    };

    //受伤数组
    String[] injureds_desc = {
            "结果%s退了半步，毫发无损。",
            "结果给%s造成一处瘀伤。",
            "结果一击命中，%s痛得弯下腰。",
            "结果%s痛苦地闷哼了一声，显然受了点内伤。",
            "结果%s摇摇晃晃，一跤摔倒在地。",
            "结果%s脸色一下变得惨白，连退了好几步。",
            "结果『轰』的一声，%s口中鲜血狂喷而出。",
            "结果%s一声惨叫，像滩软泥般塌了下去！"
    };


    //无参构造
    user() {
    }

    //有参构造
    user(String name, int blool, String gender) {
        this.name = name;
        this.blool = blool;
        this.gender = gender;
        setFace(gender);
    }

    //得到性别
    public String getGender() {
        return gender;
    }

    //设置性别
    public void setGender(String gender) {
        this.gender = gender;
    }

    //得到长相
    public String getFace() {
        return face;
    }

    //设置长相
    public void setFace(String gender) {
        Random r = new Random();
        if (gender == "男") {
            int index = r.nextInt(boyfaces.length);
            this.face = boyfaces[index];

        }
    }

    //得到姓名
    public String getName() {
        return name;
    }

    //设置姓名
    public void setName(String name) {
        this.name = name;
    }

    //得到血量
    public int getBlool() {
        return blool;
    }

    //设置血量
    public void setBlool(int blool) {
        this.blool = blool;
    }

    //输出角色信息
    public void outInfo() {
        System.out.println("姓名 "+getName());
        System.out.println("血量 "+getBlool());
        System.out.println("性别 "+getGender());
        System.out.println("长相 "+getFace());
    }

    //方法，打架过程
    //r1打了r2
    public void attack(user role) {

        //输出招式
        Random r = new Random();
        int index = r.nextInt(attacks_desc.length);
        String kungFu = attacks_desc[index];
        System.out.printf(kungFu, this.getName(), role.getName());

        //调用者造成的伤害
        int hurt = r.nextInt(45) + 1;

        //被击打者剩下的血量
        int keepBlool = role.getBlool() - hurt;

        //判断剩下的血量是否为负a
        if (keepBlool < 0) {
            keepBlool = 0;
        }
        //重新赋值给被击打者设置血量
        role.setBlool(keepBlool);

        if (keepBlool > 90) {
            System.out.printf(injureds_desc[0], role.getName());
        } else if (keepBlool > 80) {
            System.out.printf(injureds_desc[1], role.getName());
        } else if (keepBlool > 70) {
            System.out.printf(injureds_desc[2], role.getName());
        } else if (keepBlool > 60) {
            System.out.printf(injureds_desc[3], role.getName());
        } else if (keepBlool > 40) {
            System.out.printf(injureds_desc[4], role.getName());
        } else if (keepBlool > 20) {
            System.out.printf(injureds_desc[5], role.getName());
        } else if (keepBlool > 10) {
            System.out.printf(injureds_desc[6], role.getName());
        } else {
            System.out.printf(injureds_desc[7], role.getName());
        }

        //输出被击打着剩余的血量
        System.out.println(role.getName() + "剩余" + keepBlool + "血量");

    }

}

package com.myjava.playgame;

public class test {
    public static void main(String[] args) {

        //创建对象
        user r1 = new user("角色1", 100, "男");
        user r2 = new user("角色2", 100, "男");

        //输出对象信息
        r1.outInfo();
        System.out.println("-----------------");
        r2.outInfo();
        System.out.println("-----------------");

        //调用击打方法
        while (true) {

            r1.attack(r2);
            if (r2.getBlool() == 0) {
                System.out.println(r1.getName() + " KO了 " + r2.getName());
                break;
            }
            r2.attack(r1);
            if (r1.getBlool() == 0) {
                System.out.println(r2.getName() + " KO了 " + r1.getName());
                break;
            }

        }

    }
}

输出结果：
