If you’ve dabbled in programming and understand basic Java syntax but find yourself asking, “What exactly is Object-Oriented Programming (OOP)?”, then this Udemy course, “JavaシリーズVol.2【Javaオブジェクト指向の実践】プログラムは少し組める。でもオブジェクト指向って何？”, is precisely what you need.
This course is not for absolute beginners; it assumes you have a foundational understanding of programming. For those starting from scratch, the instructor highly recommends their “Java Series Vol. 1” course. However, if you’re ready to dive into the core concepts of OOP, this course excels at demystifying what can often be a confusing topic.
The instructor emphasizes a supportive learning environment, promising prompt answers to any questions, which is invaluable when tackling complex programming paradigms. The course kicks off with a clear guide to setting up your development environment using Eclipse, a popular and free IDE. The instructor walks you through the JDK download and installation process, ensuring you can start coding without any environmental hurdles.
The core of the course revolves around understanding how to work with ‘things’ or objects in programming, much like you work with numbers and characters. The examples provided, such as ’employees’ in an attendance system or ‘products’ in a sales system, are highly relatable and clearly illustrate the practical application of OOP. You’ll learn to create object blueprints, starting with a practical example of building a ‘Product’ Beans class. The course covers defining necessary data fields like `itemID`, `itemName`, `itemPrice`, and `itemStock`, and shows how Eclipse can automate the generation of these classes.
Constructors, essential for initializing objects, are explained and built together. The course then seamlessly integrates OOP with the MVC (Model-View-Controller) pattern. You’ll learn how to structure your code by defining business logic in the Model, handling display in the View, and managing the flow between them in the Controller. This approach leads to more organized and efficient code.
The practical application continues with displaying objects using `ArrayList` and `HashMap` within the View class, demonstrating how to create clean and efficient code. The Model section focuses on writing the logical processing required for business requirements, again emphasizing efficiency and clarity. Finally, the course touches upon exception handling, a crucial aspect of robust programming, teaching you how to manage errors without crashing your system.
Overall, ‘Java Series Vol. 2’ provides a well-structured and practical introduction to Object-Oriented Programming in Java. It bridges the gap between basic syntax and true object-oriented design, equipping you with the skills to write cleaner, more maintainable, and scalable Java applications.
