Abstract classes allow common behaviors while prohibiting direct instantiation, enabling inheritance. Interfaces expand upon abstraction by acting as contracts with method headers, ensuring implementation flexibility.

L’Héritage en Java

It covers advanced topics like method overriding and overloading, along with constructors in derived classes and their relation to base class construction. Practical exercises aim to implement concepts by creating classes and demonstrating inheritance through behavioral methods and attribute management.

It introduces tasks such as extending a 'Point' class to create a 'PointCol' class with RGB color attributes and related methods. Additionally, it involves modeling an enterprise's employee management system using a hierarchy of classes: 'Salarie', 'Employe', and 'Vendeur,' employing respective constructors, getters/setters, and methods for displaying and calculating salaries.
