Question

我写了一个类来创建和战斗口袋妖怪，但我无法弄清楚如何在测试器类中调用war方法来测试我写的类。

我的任务是编写和测试模拟两个神奇宝贝之间的战斗的模拟。每个神奇宝贝都有一个健康值，一个力量值和一个速度值。运行状况，强度和速度值作为参数传递给构造函数。这些值最初必须介于1到300之间，并且最初应为非零值。完成游戏的总体思路是两个口袋妖怪将在模拟中相互“战斗”，口袋妖怪轮流攻击。（具有最高速度值的那一个每轮首先出现）攻击口袋妖怪的力量将从“攻击者”的生命值中减去。

public class Pokemon{
  private int health;
  private int strength;
  private int speed;

/**
* Constructs the pokemon
* @Require:
*    health is an integer greater than or equal to 1 but less than or equal to 300
*    strength is and integer greater than or equal to 1 but less than or equal to 300
*    speed is an integer greater than or equal to 1 but less than or equal to 300
*/
public Pokemon(int health, int strength, int speed){
  assert health >= 1;
  assert health <= 300;
  assert strength >= 1;
  assert strength <= 300;
  assert speed >= 1;
  assert speed <= 300;

  this.health = health;
  this.strength = strength;
  this.speed = speed;
}

public void battle(Pokemon pokemon1, Pokemon pokemon2){
  do{
    System.out.println(pokemon1+" begins the fight against "+pokemon2);
    pokemon2.health = pokemon2.health - pokemon1.strength;

    System.out.println(pokemon1 +" does "+ pokemon1.strength +" damage to "+
    pokemon2 +" and "+ pokemon2 +" has "+ pokemon2.health +" left.");

    pokemon1.health = pokemon1.health - pokemon2.strength;

    System.out.println(pokemon2 +" does "+ pokemon2.strength +" damage to "+ 
    pokemon1 +" and "+ pokemon1 +" has "+ pokemon1.health +" left.");

  }while(pokemon1.health >= 1 || pokemon2.health >= 1);
  if(pokemon1.health < 1)
    System.out.println(pokemon1 +" has lost the fight");
  else
    System.out.println(pokemon2 +" has lost the fight");
  }
}

public class PokemonTester{
  private Pokemon charizard;
  private Pokemon blastoise;
  private Pokemon venusaur;

public PokemonTester(){
   charizard = new Pokemon(100,50,50);
   blastoise = new Pokemon(150,25,150);
   venusaur = new Pokemon(300,10,100);
 }

public static void main(String[] args){
  Pokemon.battle(charizard, blastoise); //will not compile
 }
}

我确实意识到我还没有在轮流方面实施速度方面，因为我正努力让它发挥作用。

Answer 1

将static添加到battle功能，就像在main中一样。

此外，您无法在charizard中使用blastoise和main。非静态变量不能用于静态函数。您需要在`main

中创建局部变量

public static void main(String[] args){
    Pokemon charizard = new Pokemon(100,50,50);
    Pokemon blastoise = new Pokemon(150,25,150);
    Pokemon.battle(charizard, blastoise);
}

您还可以创建新的PokemonTester并使用它的变量：

public static void main(String[] args){
    PokemonTester tester=new PokemonTester();
    Pokemon.battle(tester.charizard, tester.blastoise);
}

您可以详细了解静态成员here

Answer 2

对我来说很好。我唯一能说的代码是你的战斗方法不是静态的。

public static void battle(Pokemon pokemon1, Pokemon pokemon2)

Answer 3

除了将战斗功能设为静态之外，我还建议进行以下更改。当我运行您的代码时，我得到：

Pokemon@6228a17f begins the fight against Pokemon@c9be777
Pokemon@6228a17f does 50 damage to Pokemon@c9be777 and Pokemon@c9be777 has 100 left.
Pokemon@c9be777 does 25 damage to Pokemon@6228a17f and Pokemon@6228a17f has 75 left.
Pokemon@6228a17f begins the fight against Pokemon@c9be777
Pokemon@6228a17f does 50 damage to Pokemon@c9be777 and Pokemon@c9be777 has 50 left.
Pokemon@c9be777 does 25 damage to Pokemon@6228a17f and Pokemon@6228a17f has 50 left.
Pokemon@6228a17f begins the fight against Pokemon@c9be777
Pokemon@6228a17f does 50 damage to Pokemon@c9be777 and Pokemon@c9be777 has 0 left.
Pokemon@c9be777 does 25 damage to Pokemon@6228a17f and Pokemon@6228a17f has 25 left.
Pokemon@6228a17f begins the fight against Pokemon@c9be777
Pokemon@6228a17f does 50 damage to Pokemon@c9be777 and Pokemon@c9be777 has -50 left.
Pokemon@c9be777 does 25 damage to Pokemon@6228a17f and Pokemon@6228a17f has 0 left.
Pokemon@6228a17f has lost the fight

名称 @ 6228a17f和@ 6228a17f并不是神奇宝贝的好名字。要更改此设置，请在构造函数中添加一个字符串类型的名称字段，并相应地使用它。战斗战斗的模拟显然是错误的，因为（a）战斗每转“开始” （b）宠物小精灵的生命值降至0或以下后，战斗不会停止。为了解决这个问题，我建议使用入口控制的while循环而不是do-while，并在第一回合之后插入break语句。应用这些更改，您的程序将运行： Pokemon:

public class Pokemon{
    private int health;
    private int strength;
    private int speed;
    private String name;
    public Pokemon(String name, int health, int strength, int speed){
        assert health >= 1;
        assert health <= 300;
        assert strength >= 1;
        assert strength <= 300;
        assert speed >= 1;
        assert speed <= 300;
        this.health = health;
        this.strength = strength;
        this.speed = speed;
        this.name = name;
    }

    public static void battle(Pokemon pokemon1, Pokemon pokemon2)
    {
        System.out.println(pokemon1.name+" begins the fight against "+pokemon2.name);
        while
        (pokemon1.health >= 1 || pokemon2.health >= 1)
        {

            pokemon2.health = pokemon2.health - pokemon1.strength;

            System.out.println(pokemon1.name +" does "+ pokemon1.strength +" damage to "+
                pokemon2.name +" and "+ pokemon2.name +" has "+ pokemon2.health +" health left.");

            if
            (pokemon2.health <= 0)
            break;

            pokemon1.health = pokemon1.health - pokemon2.strength;

            System.out.println(pokemon2.name +" does "+ pokemon2.strength +" damage to "+ 
                pokemon1.name +" and "+ pokemon1.name +" has "+ pokemon1.health +" health left.");

        }

        if
        (pokemon1.health < 1)
            System.out.println(pokemon1.name +" has lost the fight");
        else
            System.out.println(pokemon2.name +" has lost the fight");
    }
}
