Casting object: The object casting instructs the compiler to change the type of an object to another type. The objects of subclass can be assigned to the object of super class and this casting is done implicitly. This casting is called as upcasting. In java, the objects of super class are not allowed to assign to subclass object implicitly. In this case, an explicit casting should be done. This casting is called as downcasting.
