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?

Method OverridingGiven below is the code for the Rectangle class.Define a new class named Square and override the methods area() and perimeter() to calculate the area and perimeter of a square.public class Rectangle { private double width; private double height; Rectangle(double width, double height){ this.width = width; this.height = height; } public double getWidth() { return width; } public double getHeight() { return height; } public void area() { System.out.println("Area of Rectangle is: " + (width * height) ) ; } public void perimeter() { System.out.println("Perimeter of Rectangle is: " + ( (2* width) + (2* height) ) ) ; }}

A class Circle is defined in the following code:public class Circle { int radius; static String name; void getPerimeter() { } static void getArea() { }}Let c be an instance of Circle, which of the statements are correct?System.out.println(c.radius);c.getArea();c.getPerimeter();System.out.println(c.name);
