Study Notes
Inheritance in Object-Oriented Programming
- Single inheritance allows a subclass to inherit properties and methods from a single parent class.
Multiple Inheritance in Java
- Multiple inheritance is not directly supported in Java, but it can be implemented using interfaces.
Multilevel Inheritance
- Multilevel inheritance allows a subclass to serve as a base class for yet another subclass.
Limitations of Inheritance in Java
- Multiple inheritance is not directly allowed in Java.
Purpose of Inheritance
- The main concept supported by inheritance in object-oriented programming is code reuse and reduction of code length.
Hybrid Inheritance in Java
- Hybrid inheritance can be implemented through interfaces in Java.
Note: Hybrid inheritance is a combination of multiple and multilevel inheritance.
