# 人狗大战游戏的Java实现
在这篇文章中，我们将介绍一个简单的人狗大战游戏的Java实现。这个小游戏模拟人类与狗之间的战斗，每个玩家可以选择攻击或者防御。
游戏设计
我们定义两个角色：`Human`（人类）和`Dog`（狗）。每个角色都有生命值、攻击力和防御力。游戏的核心逻辑是交替进行攻击，直到其中一方的生命值降至0。
代码实现
以下是游戏的基本实现：
java
import java.util.Random;
import java.util.Scanner;
class Character {
String name;
int health;
int attackPower;
int defensePower;
public Character(String name, int health, int attackPower, int defensePower) {
this.name = name;
this.health = health;
this.attackPower = attackPower;
this.defensePower = defensePower;
}
public void attack(Character target) {
int damage = Math.max(0, this.attackPower - target.defensePower);
target.health -= damage;
System.out.println(this.name + " attacks " + target.name + " for " + damage + " damage!");
}
}
public class DogVsHumanGame {
public static void main(String[] args) {
Character human = new Character("Human", 100, 20, 5);
Character dog = new Character("Dog", 80, 15, 3);
Scanner scanner = new Scanner(System.in);
while (human.health > 0 && dog.health > 0) {
System.out.println("Your turn! (1: Attack, 2: Defend)");
int choice = scanner.nextInt();
if (choice == 1) {
human.attack(dog);
} else {
human.defensePower += 5;
System.out.println("You chose to defend.");
}
if (dog.health > 0) {
dog.attack(human);
}
System.out.println("Human Health: " + human.health);
System.out.println("Dog Health: " + dog.health);
}
if (human.health <= 0) {
System.out.println("Human is defeated! Dog wins!");
} else {
System.out.println("Dog is defeated! Human wins!");
}

scanner.close();
}
}

总结
在这个简单的人狗大战游戏中，我们使用了面向对象的设计思想，创造了一个角色类来封装属性和行为。用户通过控制选择攻击或防御，使得游戏充满趣味性。在今后的改进中，可以加入更多的技能、道具系统以及更复杂的游戏逻辑。希望这个示例能够激发大家对Java编程的兴趣！
