설명되지 않음 "추상이 아니며 추상적 인 방법을 무시하지 못함"오류

Question

내가 시도하고있는 게임에서이 오류를 설명 할 수 없습니다. 저는 게임 프로그래밍을 처음 접했고 YouTube 튜토리얼을 따라 가고 있습니다. 내가 알 수있는 한, 비디오에서와 똑같이하고 있지만 여전히이 오류가 발생합니다.

내가 (같은 추상적 인 방법 다이를 구현); 돌과 나무 수업에서도. 나는이 오류가 왜 발생하는지 이해할 수 없다. 누구든지 설명해 주겠니? NetBeans를 다시 시작하여 코드를 다시 작성하려고했습니다. 최소화

Answer 1

귀하의 코드 (check how to create a MVCE가) 정확하고 오류가 발생하지 않습니다

abstract class Entity { 
    public abstract void die(); 
} 

class Player extends Creature{ 

    @Override 
    public void die() { 
     System.out.println("You died"); 
    } 
} 

abstract class Creature extends Entity{ 
} 

그래서 당신의 수입을 확인을, 다른 패키지에 추가 Player 클래스가있을 수 있습니다.
