Which two classes use the Shape class correctly?A. public class Circle implements Shape   {  private int radius;  }B. public abstract class Circle extends Shape   {  private int radius;  }C. public class Circle extends Shape   {  private int radius;  public void draw();  }D. public abstract class Circle implements Shape   {  private int radius;  public void draw();  }E. public class Circle extends Shape   {  private int radius;  public void draw()  {   /* code here */  }  }F. public abstract class Circle implements Shape   {   private int radius;   public void draw()    {    /* code here */    }  }OptionsA,CB,EC,ET,H

Which would declare a compilable abstract class?Select one:a.public abstract class Shape { public Square draw(); }b.public abstract class Shape { public Square draw() { } }c.public class Shape abstract { public abstract Square draw(); }d.public class Shape { public abstract Square draw(); }

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);

Consider the following class diagram. Which class correctly implements the Drawable interface?a.class Circle { int radius; void draw() {} }b.class Circle implements Drawable { int radius; void draw() {} }c.class Circle implements Drawable { int radius; }d.class Circle implements Drawable { void draw() {} }

Let's consider an abstract class called Shape, which has two(2) concrete methods, paintShape() and copyShape(), and one(1) abstract method, calculateArea(). Additionally, we have two(2) concrete classes, Circle and Square, that extends the Shape class. What methods should be included in the Circle and Square subclasses to prevent compilation errors?a.subclasses will not need to implement other methods as all can be inherited from the parent class - Shape.b.copyShape(),paintShape() and calculateArea ()c.copyShape() and paintShape()d.calculateArea ()

Find OutputType the correct output for the code given below. Also, explain the reason behind your answer.class Shape { public Shape() { System.out.println("inside Shape class default constructor"); }}class Rectangle extends Shape { public Rectangle() { System.out.println("inside Rectangle class default constructor"); }}class Square extends Rectangle { public Square() { System.out.println("inside Square class default constructor"); }}public class ConstructorChain { public static void main(String[] args) { Square sq = new Square(); }}
