java - 简单程序中的 StackOverflowError

Question

亲爱的，我想实现这个行为:

“闯入者枪毙，幸存者再枪毙”

但是我得到了这个堆栈跟踪:

Exception in thread "main" java.lang.StackOverflowError
    at java.lang.String.equals(String.java:975)
    at test.Person.isDead(Person.java:14)
    at test.Shooter.shoot(Shooter.java:7)
    at test.Shooter.shoot(Shooter.java:8)

“属性”类:

package test;

public class Property {

    private Shooter shooter = new Shooter();

    public void punish(Person tresspasser) {

        shooter.shoot(tresspasser);
    }
}

射手类:

package test;

public class Shooter {

    public void shoot(Person person) {

        if(!person.isDead()){
            shoot(person);
        }
    }
}

“人”类:

package test;

public class Person {

    private String name;

    public Person(String name) {

        this.name = name;
    }

    public void tresspass(Property property) {

        property.punish(this);
    }

    public boolean isDead(){

        return !name.equals("Chuck Norris");
    }
}

最后是主类:

package test;

public class Main {

    public static void main(String args[]) {

        Person person = new Person("Chuck Norris");

        Property myProperty = new Property();

        person.tresspass(myProperty);
    }
}

我做错了什么？

我使用 eclipse，问题出现在 Java 6、7 和 8 中...

Answer 1

return !name.equals("Chuck Norris"); 如果此人的名字是“Chuck Norris”，则始终返回 false，因此您会无限循环。

您的弹药可能有限，因此您应该考虑某种弹药功能。
