2:1.玩家类pk增加暴击
增加物品掉落（击杀敌人后随机掉落物品） 实体类
package comm.hp.yun.demo2;
import java.util.Random;
public class Player {
public String name;
public String type;
public int life;
public int defense;
public int attack;
Random a = new Random();
Random b = new Random();
Random c = new Random();
public void say(){
System.out.println("我是"+name+",是一个"+type);
System.out.println("生命值"+life+"防御值"+defense+"攻击力"+attack);
}
public void pk(Player p){
int flag = 0;
//回合制，直至一方死亡
while (true) {
this.say();
p.say();
if (flag == 0) {
int harm = this.attack - p.defense;
int t = b.nextInt(2);
if (t!=0){
System.out.println(p.name + "掉血" + harm);
p.life -= harm;
}else {
System.out.println("暴击");
System.out.println(p.name + "掉血" + harm*2);
p.life -= harm*2;
}
flag = 1;
} else {

int l = c.nextInt(2);
if (l!=0){
System.out.println(this.name + "掉血" + harm);
this.life -= harm;
}else {
System.out.println("暴击");
System.out.println(this.name + "掉血" + harm*2);
this.life -= harm*2;
}
flag = 0;
}
//有血量<=0，战斗结束
if(this.life<=0){
System.out.println(p.name+"打败了"+this.name);
break;
}
if(p.life<=0){
System.out.println(this.name+"打败了"+p.name);
break;
}
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
String [] stu = {"奖励100经济","破军","名刀司命","碎星锤","美女一个"," "};
for (int z = 0; z < stu.length; z++) {
z = a.nextInt(6);
System.out.println("恭喜你获得了胜利"+stu[z]);
break;
}
}
//构造器
public Player() {
}

测试类
package comm.hp.yun.demo2;
public class PlayerTest {
public static void main(String[] args) {
//选英雄阶段
Player p1 = new Player("韩信", "刺客", 1000, 120, 300);
Player p2 = new Player("瑶", "辅助", 2200, 330, 280);
//开始决斗
p1.pk(p2);
}
}
3.柜台商品管理系统
实体类：Goods
package comm.hp.yun.demo3;
public class Goods {
//属性
private int id;//商品号
private String goodsName;//商品名称
private int price;//商品价格
private String desc;//商品描述
//封装get方法
public int getId() {
return id;
}
public String getGoodsName() {
return goodsName;
}
public int getPrice() {
return price;
}
public String getDesc() {
return desc;
}
//封装set方法
public void setId(int id) {
this.id = id;
}
public void setGoodsName(String goodsName) {
this.goodsName = goodsName;
}
public void setPrice(int price) {
this.price = price;
}
public void setDesc(String desc) {
this.desc = desc;
}
//无参构造器
public Goods(){
}
//重写toString方法
@Override
public String toString() {
return "Goods{" +
"id=" + id +
", goodsName='" + goodsName + ''' +
", price=" + price +
", desc='" + desc + ''' +
'}';
}
//有参构造器 有参构造器初始化初始化商品对象
public Goods(int id, String goodsName, int price, String desc) {
this.id = id;
this.goodsName = goodsName;
this.price = price;
this.desc = desc;
}
}
柜台类：Counter
package comm.hp.yun.demo3;
public class Cunter {
//属性：
//柜台商品列表，固定10个商品位置
private Goods[] fan=new Goods[10];
//柜台商品数量
private int num;
//构造器： 无参构造器初始化2个商品
public Cunter(){
this.fan[0]=new Goods(1,"巧克力",25,"美味可口，恋爱必备！");
this.fan[1]=new Goods(2,"卫龙辣条",2,"隔壁小孩馋哭了！");
this.fan[2]=new Goods(3,"红茶",30,"冰爽可口");
this.fan[3]=new Goods(4,"香蕉",10,"香甜可口");
num=4;//相当于四个商品
}
//展示柜台所有的商品(不能输出null)
public void show(){
for (Goods yun:fan){
if (yun !=null){
System.out.println(yun);
}
}
}
}
测试类：CounterTest
package comm.hp.yun.demo3;
public class CounterTest {
public static void main(String[] args) {
//创建柜台对象
Cunter fan=new Cunter();
//调用show()方法展示柜台商品
fan.show();
}
}
