Description

Java : Mastering Object-Oriented Programming & Application Development

This Java Core Course provides a strong foundation in Java programming, focusing on both fundamental concepts and practical applications. You’ll start with the basics, including JDK, JVM, and JRE, and write your first “Hello World” program using Eclipse IDE. The course covers essential programming elements such as data types, control structures, methods, arrays, and strings, helping you build a solid understanding of Java syntax and logic.

As you progress, you’ll dive into object-oriented programming (OOP) concepts like Encapsulation, Inheritance, Polymorphism, and Abstraction, enabling you to write structured and maintainable code. You’ll also learn advanced topics such as exception handling, the collection framework, file handling, and multi-threading to create robust and high-performance applications.
