Developers need to check whether a data type is compatible with the assigned data type or not. From the above example, it can be clearly understood that we can not access child class members using a parent class reference even though it is of the child type. The compiler will now automatically cast a subtype value to a supertype object. If the data types are compatible, then java does automatic conversion and does not require casting.
