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 ()

Which method in an abstract class must be overridden in its subclasses?   Concrete methodsAbstract methodsClass methodsStatic methods

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(); }

ct the correct answerWhich of these class relies upon its subclasses for complete implementation of its methods?

Which keyword is used to prevent a method from being overridden in the subclass?Question 4Answera.finalb.staticc.abstractd.private
