Polymorphism means the ability to take more than one form. An operation may exhibit different behaviors in different instances. The behavior depends on the data types used in the operation
Advantages of polymorphism:
- Same interface could be used for creating methods with different implementations
- Reduces the volume of work in terms of distinguishing and handling various objects
- Supports building extensible systems
- Complete implementation can be replaced by using same method signatures
Advantages of dynamic binding:
- Compiling time is much lower and allows faster development
- The current state of the program is better known to the runtime linker, so that the memory and its resources can easily be reordered
- The addresses symbols which may not be known at compile time, can be resolved by the runtime linker. This process is ideal for networked systems
- Common resources could well be shared instead of duplicating them in each time of execution.
