You have a class Shape:public class Shape { protected String name; protected int area; protected int perimeter; public Shape(){ } public Shape(String name, int area, int perimeter){ this.name = name; this.area = area; this.perimeter = perimeter; } public int getArea(){ return area; } public int getPerimeter(){ return perimeter; }}You have a child class Circle:public class Circle extends Shape { public Circle(String name, int area, int perimeter){ super(name, area, perimeter); } public int getArea(){ return area; } @Override public int getCircumference(){ return perimeter; }}What is the error in the definition of Circle?
