This course provides a comprehensive introduction to Object-Oriented Programming (OOP) using Java, covering foundational and advanced topics. Starting with OOP principles, students will learn about classes, objects, and terminology through practical exercises like creating a Motor Bike Java class and working with book instances. The course delves into: - Encapsulation, abstraction, and constructors, reinforced by exercises and puzzles. - Primitive data types and their alternatives, with in-depth explanations and exercises on Java integer, floating point, Boolean, and character data types. Puzzles and real-world problems enhance understanding. - Conditionals, loops, and reference types build a strong programming foundation through practical application. The course explores arrays and ArrayLists, teaching students to create, access, and manipulate them with numerous exercises. Finally, a deeper dive into class design, inheritance, and polymorphism prepares students for complex programming challenges. Designed for aspiring Java developers, programming enthusiasts, and computer science students with basic programming knowledge, this course requires no prior Java experience.
