Java로 배우는 객체 지향 프로그래밍 입문

Explore the fundamentals of object-oriented programming (OOP) in Java, focusing on the distinctions between primitive data types and objects. Learn to define and create classes and objects and understand the critical components of classes, such as fields, constructors, and methods.

Deep dive into object-oriented programming by exploring key concepts such as encapsulation, inheritance, and abstraction. Learn how to control access to class members, extend class functionality, and define abstract concepts and contracts that ensure consistency across implementations.

Strengthen your object-oriented programming skills by exploring how Java interfaces and polymorphism work. Learn how to define interfaces and implement them in classes to support flexible behavior. Practice method overriding to customize behavior in subclasses and use method overloading to define multiple forms of a method within the same class. You’ll also explore constructor overloading to enable versatile object creation. These hands-on exercises will help you write more adaptable and reusable Java code.
