About this course

The aim of this course is for students to master platform-independent object-oriented programming with Java as the foundation for advanced technologies like web applications, cloud computing, and enterprise systems. Students will learn to design, implement, test, and debug Java applications using object-oriented principles. The course emphasizes hands-on programming experience through practical exercises and projects that reinforce theoretical concepts and develop problem-solving abilities.
