Java 语法错误，插入"；EnumBody“；及；枚举标识符“；在爪哇

如果有人能帮上忙，我想不出我的代码出了什么问题，为什么它会告诉我这些？它给了我一个toString方法的错误。。。为什么要插入枚举体和标识符？多谢各位

  import java.lang.String;

  public class Circle extends Shape {
  private double radius;

  public Circle( double theRadius ){
    super();
    if ( theRadius <= 0.0 )
        setRadius( Shape.DEFAULT_SIZE );
    else
        setRadius( theRadius );
}



public double getSurfaceArea(){

    return this.radius * this.radius * Math.PI;
}

public double getPeremeter(){
    ;
    return 2 * this.radius + Math.PI;
}

public double getRadius(){
    return this.radius;

}

public void setRadius( double theRadius ) {
    if( theRadius <= 0 )
        return;
    this.radius = theRadius;
}

@Override
public double getPerimeter() {
    // TODO Auto-generated method stub
    return 0;



     public String toString() {
         return "Circle Surface Area "+getSurfaceArea()+", Circle Peremeter "       +getPerimeter();
     }
}

@Override
public double getSizeAmount() {
    // TODO Auto-generated method stub
    return 0;
}
   }

查看您的

getperiment

方法：

@Override
public double getPerimeter() {
    // TODO Auto-generated method stub
    return 0;



     public String toString() {
         return "Circle Surface Area "+getSurfaceArea()+", Circle Peremeter "
              +getPerimeter();
     }
}

您正试图在

getperiment

方法中声明

toString

方法

代码的缩进应该给您一个提示——这是适当缩进代码很重要的原因之一。你应该：

@Override
public double getPerimeter() {
    // TODO Auto-generated method stub
    return 0;
}    

@Override
public String toString() {
    return "Circle Surface Area " + getSurfaceArea() + ", Circle Perimeter "       
        + getPerimeter();
}

应分为两部分：

@Override
public double getPerimeter() {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public String toString() {
             return "Circle Surface Area "+getSurfaceArea()+", Circle Peremeter "       +getPerimeter();
         }

班级的形状是什么样的？您在类Circle中缺少getPermission（）的括号，不确定这是否会导致所有错误？

@Override
public double getPerimeter() {
    // TODO Auto-generated method stub
    return 0;
}    

@Override
public String toString() {
    return "Circle Surface Area " + getSurfaceArea() + ", Circle Perimeter "       
        + getPerimeter();
}

@Override
public double getPerimeter() {
    // TODO Auto-generated method stub
    return 0;



     public String toString() {
         return "Circle Surface Area "+getSurfaceArea()+", Circle Peremeter "       +getPerimeter();
     }
}

@Override
public double getPerimeter() {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public String toString() {
             return "Circle Surface Area "+getSurfaceArea()+", Circle Peremeter "       +getPerimeter();
         }
