Polymorphism: Ability to present the same interface for different data types.
Abstraction: Hiding the complex impleme...

Exceptions in inheritance can be handled by using try-catch blocks in the derived class.
Use try-catch blocks in the derived class to catch exceptions thrown by the base class methods.
Handle exceptions specific to the derived class in the catch block.
Consider using super() to call the base class constructor within the try block.
Avoid catching general exceptions unless necessary to maintain code clarity.
