Learn Java from Scratch - A Beginner's Guide - Step 13 - Java Abstract Class – Introduction

The video tutorial introduces the concept of abstract classes in programming. It explains how abstract classes allow for the declaration of methods without providing implementations, which must be defined in subclasses. The tutorial demonstrates creating a class with methods, defining abstract methods, and extending abstract classes to create concrete classes. It concludes with a summary of key points and a preview of the next topic.

Describe the process of defining an abstract class in code.

What happens if a subclass does not provide an implementation for an abstract method?
