Dynamic casting is safely discovering the type of an object instance at runtime.
This is achieved by the compiler generating reference tables, which can be potentially rather large. For this reason, it is often disabled during compilation if the programmer knows that they do not use the feature.

In data hiding we use modifiers like private, public and protected to hide the java variable and methods visibility.
When we go with the abstraction by bean of abstract classes and method we define a behavior and method. That is like skeleton for any class that would be extending this class.

Dynamic loading is a mechanism by which a computer program can, at run time, load a library into memory, retrieve the addresses of functions and variables contained in the library, execute those functions or access those variables, and unload the library from memory.

Dynamic cast:
Dynamic casts can be used to safely cast a superclass reference into a reference to a subclass in a class hierarchy.
Dynamic binding:
Determining at run time what method to invoke.
Data hiding:
Expose only necessary information to the client.

Dynamic cast is used to convert pointers and references at run-time, generally for the purpose of casting a pointer or reference up or down an inheritance chain (inheritance hierarchy).
