Fundamentals Of Object-Oriented Programming: Java and IntelliJ - Multi-level Inheritance, Polymorphism

The video tutorial explains the concept of inheritance in object-oriented programming using a Vehicle class hierarchy. It demonstrates how to translate a UML diagram into Java code by creating a Vehicle class with properties and methods, then extending it to create a Car class and further extending to a SportsCar class. The tutorial covers constructors, method overriding, and polymorphism, and concludes with testing the classes to show different implementations of methods.
