+ Learn important software design rules and best practices for writing well-designed code.

+ Gaining hands-on experience through an instructor-led project following professional coding conventions.

This course ensures that you not only enhance your Core Java knowledge but also adopt industry-standard best practices, preparing you for real-world Java development and making you industry-ready. Additionally, a special module is included on using Git & GitHub professionally from within Eclipse.

Course Description

Deepen Your Core Java Knowledge!

This course is designed for students who have completed the foundational object-oriented programming course and are ready to build on their core Java knowledge. It delves into advanced core Java topics while emphasizing best practices and software design rules essential for writing professional Java code.

After a brief introduction to debugging Java programs and JUnit testing in Eclipse, the course begins with an instructor-led Java EE project, which is progressively developed throughout the course as new concepts are introduced. This project serves as a practical foundation that will be expanded into a complete Web application, incorporating database (MySQL) and front-end technologies (Servlets & JSP) in our follow-up course.

Key topics covered include:

  • JVM Internals
  • Exception Handling with Best Practices
  • Input/Output (java.io)
  • Collections Framework and Basic Generics
  • Basic Multithreading
  • Using Git & GitHub from within Eclipse
Be certified as Core Java Engineer!

You can also earn our Core Java Engineer! certification - our endorsement that you've mastered Core Java. To achieve this certification, you must not only complete all course lectures and quizzes but also successfully complete the following programming assessments, each verified by our expert engineers.

  • Instructor-led project
  • Mini-Project - Implementing a simple Java compiler

This is hands down the greatest online course I've ever taken ... To really benefit from this course, you'll have to sit there and bang your head but if you take careful notes and make sure you can explain each step you're taking to solve a problem, you'll come out on top. I am now a data engineer and this course is one of the biggest catalysts for my transition into tech.
