Java OOP: Leverage Object-Oriented Programming for Efficient Code

Explore the principles of Object-Oriented Programming (OOP) in Java, where objects encapsulate data and methods. Learn how OOP provides significant advantages such as faster execution, clearer program structure, better code maintainability, and reusable applications, all while adhering to the DRY (Don't Repeat Yourself) principle.

Java OOP

OOP stands for Object-Oriented Programming. It involves creating objects that contain both data and methods, unlike procedural programming which focuses on writing procedures that perform operations on data.

Advantages of OOP:

• Faster and easier to execute
• Provides a clear structure for programs
• Helps keep Java code DRY ("Don't Repeat Yourself")
• Makes code easier to maintain, modify, and debug
• Enables the creation of reusable applications with less code and shorter development time

Tip: The DRY principle is about reducing code repetition. Extract common code to a single place and reuse it instead of repeating it.

Classes and Objects

Classes and objects are the core of OOP. A class is a template for objects, and an object is an instance of a class. When objects are created, they inherit all variables and methods from the class.
