Constructors and Methods

A constructor is a special method (not appropriate to call it a method but for the sake of analogy) whose task is to initialize the object of its class.It is special because its name is the same as the class name.They do not have return types, not even void and therefore they cannot return values. They cannot be inherited, though a derived class can call the base class constructor. Constructor is invoked whenever an object of its associated class is created.
