Assume Cylinder is a subtype of Circle. Analyze the following code: _____Circle c = new Circle (5);Cylinder cy = c;A. The code has a compile error.B. The code has a runtime error.C. The code is fine.
Solution
The code will have a compile error.
In Java, you can't directly assign an instance of a superclass (Circle) to a variable of its subclass (Cylinder). This is because a subclass may have additional properties and methods that the superclass doesn't have.
In this case, a Cylinder (the subclass) is a specific type of Circle (the superclass) that has additional properties like height. When you create a new Circle, it doesn't have these additional properties. So, if you try to assign it to a Cylinder variable, the compiler doesn't know how to handle these missing properties and you get a compile error.
To fix this, you could either create a new Cylinder instead of a new Circle, or you could use casting if you're sure that your Circle object is actually an instance of Cylinder. But casting without being sure can lead to a runtime error if the object is not actually an instance of the subclass.

Suppose you create a class Square to be a subclass of GeometricObject. Analyze the following code and choose the correct statement from the options given below.class Square extends GeometricObject { double length; Square(double length) { GeometricObject(length); }}Group of answer choicesThe program compiles fine, but you cannot create an instance of Square because the constructor does not specify the length of the Square.The program has a compile error because you attempted to invoke the GeometricObject class's constructor illegally.The program compiles fine, but it has a runtime error because of invoking the Square class's constructor illegally.The program has no compile time or run time errors.
