Suppose you create a class Square to be a subclass of GeometricObject. Analyze the following code: public class Square extends GeometricObject { private double length;   public Square(double length) { length = length; } }      The program doesn't compile because you did not call the GeometricObject constructor.   The program doesn't compile because the length is not initialized.    The program compiles and runs correctly.   The program compiles but the length is not set correctly.

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.
