写一个Java代码,设计一个僵尸游戏的应用程序,满足以下要求: (1)僵尸作为父类(抽象类),其衍生出不同的子类,每个子类具有类似的功能(如前进方式、攻击方式等),但功能的实现过程不同: (2)每个子类实现了类似的接口(如连续发射、扔雷等),但接口的实现过程不同;(3)应用程序具备从命令行(键盘)接收数据的能力;(4)组件放在不同的包中; (5)整个应用程序的设计符合“开-闭”原则;

好的,我可以为你提供一个Java代码示例,符合你的要求。以下是一个基本的僵尸游戏应用程序的代码,其中包含了一个抽象类 `Zombie`、两个实现类 `NormalZombie` 和 `FastZombie`、两个接口 `Shootable` 和 `ThrowGrenadeable`、一个游戏类 `Game`,以及一个测试类 `TestGame`。
`Zombie` 类:
```java
package com.example.zombiegame.zombies;
public abstract class Zombie {
protected String moveMethod;
protected String attackMethod;
public Zombie(String moveMethod, String attackMethod) {
this.moveMethod = moveMethod;
this.attackMethod = attackMethod;
}
public abstract void move();
public abstract void attack();
}
```
`NormalZombie` 类:
```java
package com.example.zombiegame.zombies;
import com.example.zombiegame.interfaces.Shootable;
import com.example.zombiegame.interfaces.ThrowGrenadeable;
public class NormalZombie extends Zombie implements Shootable, ThrowGrenadeable {
public NormalZombie(String moveMethod, String attackMethod) {
super(moveMethod, attackMethod);
}
@Override
public void move() {
System.out.println("Normal Zombie moves by " + moveMethod);
}
@Override
public void attack() {
System.out.println("Normal Zombie attacks by " + attackMethod);
}
@Override
public void shoot() {
System.out.println("Normal Zombie shoots continuously");
}
@Override
public void throwGrenade() {
System.out.println("Normal Zombie throws grenade");
}
}
```
`FastZombie` 类:
```java
package com.example.zombiegame.zombies;
import com.example.zombiegame.interfaces.Shootable;
import com.example.zombiegame.interfaces.ThrowGrenadeable;
public class FastZombie extends Zombie implements Shootable, ThrowGrenadeable {
public FastZombie(String moveMethod, String attackMethod) {
super(moveMethod, attackMethod);
}
@Override
public void move() {
System.out.println("Fast Zombie moves by " + moveMethod);
}
@Override
public void attack() {
System.out.println("Fast Zombie attacks by " + attackMethod);
}
@Override
public void shoot() {
System.out.println("Fast Zombie shoots intermittently");
}
@Override
public void throwGrenade() {
System.out.println("Fast Zombie throws grenade");
}
}
```
`Shootable` 接口:
```java
package com.example.zombiegame.interfaces;
public interface Shootable {
void shoot();
}
```
`ThrowGrenadeable` 接口:
```java
package com.example.zombiegame.interfaces;
public interface ThrowGrenadeable {
void throwGrenade();
}
```
`Game` 类:
```java
package com.example.zombiegame;
import com.example.zombiegame.zombies.Zombie;
import java.util.Scanner;
public class Game {
public static void play(Zombie zombie) {
Scanner scanner = new Scanner(System.in);
System.out.println("Enter command (attack, move, shoot, grenade): ");
String command = scanner.nextLine();
switch (command) {
case "attack":
zombie.attack();
break;
case "move":
zombie.move();
break;
case "shoot":
if (zombie instanceof Shootable) {
((Shootable) zombie).shoot();
} else {
System.out.println("This zombie cannot shoot");
}
break;
case "grenade":
if (zombie instanceof ThrowGrenadeable) {
((ThrowGrenadeable) zombie).throwGrenade();
} else {
System.out.println("This zombie cannot throw grenade");
}
break;
default:
System.out.println("Invalid command");
}
}
}
```
`TestGame` 类:
```java
package com.example.zombiegame;
import com.example.zombiegame.zombies.FastZombie;
import com.example.zombiegame.zombies.NormalZombie;
import com.example.zombiegame.zombies.Zombie;
public class TestGame {
public static void main(String[] args) {
Zombie normalZombie = new NormalZombie("walking", "biting");
Zombie fastZombie = new FastZombie("running", "scratching");
Game.play(normalZombie);
Game.play(fastZombie);
}
}
```
在 `TestGame` 类中,我们创建了一个 `NormalZombie` 和一个 `FastZombie` 的实例,并调用 `Game` 类中的 `play` 方法,从命令行接收用户输入的命令,并根据用户的输入执行相应的操作。
这个应用程序符合“开-闭”原则,因为我们可以轻松地添加新的子类或接口,而不需要修改现有的代码。例如,如果我们想要添加一个 `FlyingZombie` 类,它可以飞行而不是走路,我们可以轻松地创建这个新类而不会影响现有的代码。
