Course Description

Object Oriented Programming with Java

Object-oriented programming (OOP) is one of the most common paradigms used in multiple industries and areas. Similarly, Java is one of the most used languages in several areas, from software development to data engineering. This course covers the fundamental concepts of OOP in Java, which allow clean, reusable, and maintainable software to be built.

Introduction to OOP in Java

The course starts by explaining OOP and why it is an essential paradigm in software development. We'll then review the structure of a Java program and how to create classes and objects using fields, methods, and constructors.

Implementing OOP in Java

After reviewing the basic Java and OOP knowledge, Chapter 2 will take you through more advanced concepts for implementing OOP in Java. ⁤⁤You'll explore access modifiers, encapsulation, inheritance, and interfaces— crucial concepts for creating structured and efficient code. The course also reviews implementations of built-in data types like Lists or Maps and advanced topics like polymorphism, ensuring a deep understanding of OOP in Java.

By the end of this course, you will have a broad understanding of OOP in Java, enabling you to write clean, reusable, and maintainable code.
