java找不到符号变量super

你好，我被卡住了，无法理解为什么这不起作用。我正在尝试使用继承和重写，但我一直遇到这个错误。在过去的一个小时里，我一直在想这个问题，但是没有任何线索。我可能错过了一些愚蠢的事情，任何帮助都将不胜感激

public class FlyingDragon extends Entity {
private int Hp;
public FlyingDragon(int x, int y, int Hp){
    super (x, y);
    this.Hp = Hp;
}
public void setHp(int Hp){
    this.Hp = 100;
}

public int getHp(){
   return Hp;}

public void setType(String type) { ###error is here
 super.setType("Flying Dragon");}
}

    public abstract class Entity { 
private char symbol; // symbol that represents the entity
private String type; // every entity is of a type
private int x; // x coordinate in the room
private int y; // y coordinate in the room


 public Entity (int x, int y) {
 type = "entity";
 this.x=x;
 this.y =y;
}



 public char getSymbol() {
   return symbol;
  }

 public void setSymbol(char c) {
     symbol = c;
  }

 public int getX() {
   return x;
  }

  public int getY() {
   return y;
  }
  public void setX (int newx) {
     this.x=newx;

   }

   public void setY (int newy) {
     this.y=newy;

   }
    public String getType() {
      return type;
     }

  public void setType(String type) {
     this.type = type;
     }
  }

将

FlyingDragon

的方法

setType

更改为：

public void setType(String type) {
        super.setType("Flying Dragon");
    }

试试这个：

为实体类创建单独的文件将所有实体代码放入该类

实体类：

public abstract class Entity { 
private char symbol; // symbol that represents the entity
private String type; // every entity is of a type
private int x; // x coordinate in the room
private int y; // y coordinate in the room


 public Entity (int x, int y) {
 type = "entity";
 this.x=x;
 this.y =y;
}



 public char getSymbol() {
   return symbol;
  }

 public void setSymbol(char c) {
     symbol = c;
  }

 public int getX() {
   return x;
  }

  public int getY() {
   return y;
  }
  public void setX (int newx) {
     this.x=newx;

   }

   public void setY (int newy) {
     this.y=newy;

   }
    public String getType() {
      return type;
     }

  public void setType(String type) {
     this.type = type;
     }
    }

  public class Test {

    public static void main(String[] args)  {

        FlyingDragon d = new FlyingDragon(1,2,3);

        //whatever you want to do here
    }
}

现在为FlyingDragon创建单独的类

飞龙班

public class FlyingDragon extends Entity {
private int Hp;
public FlyingDragon(int x, int y, int Hp){
    super(x, y);
    this.Hp = Hp;
}
public void setHp(int Hp){
    this.Hp = 100;
}

public int getHp(){
   return Hp;}

public void setType(String type) { //###error is here
 super.setType("Flying Dragon");}
}

测试类：

public abstract class Entity { 
private char symbol; // symbol that represents the entity
private String type; // every entity is of a type
private int x; // x coordinate in the room
private int y; // y coordinate in the room


 public Entity (int x, int y) {
 type = "entity";
 this.x=x;
 this.y =y;
}



 public char getSymbol() {
   return symbol;
  }

 public void setSymbol(char c) {
     symbol = c;
  }

 public int getX() {
   return x;
  }

  public int getY() {
   return y;
  }
  public void setX (int newx) {
     this.x=newx;

   }

   public void setY (int newy) {
     this.y=newy;

   }
    public String getType() {
      return type;
     }

  public void setType(String type) {
     this.type = type;
     }
    }

  public class Test {

    public static void main(String[] args)  {

        FlyingDragon d = new FlyingDragon(1,2,3);

        //whatever you want to do here
    }
}

您将setter定义为

setType

，但使用了

type

。仍然是相同的错误，但感谢您的建议为什么要重写setter？假设

公共抽象类实体{}

最后缺少一个}。是的，很抱歉它不在我的程序中，再次感谢您的输入，但仍然没有工作，谢谢你的意见！还有什么问题吗？完全相同的错误，找不到符号变量super请尝试将这两个类放在单独的中。java文件不可编译源代码-错误的树类型，这就是我在使用哪个IDE时遇到的错误？请确保在使用其源代码时，也获得了

公共类测试{

在他的测试类中。它不在正常代码部分，因此您可能错过了netbean上的.im
