Hi Friends, this course is specially designed for students who do not have prior coding experience. Course covers all the Core Java Concepts from basic to advanced levels along with practical examples and coding exercises.

This course covers Core Java topics in detail from basic to advanced levels. I believe in example-oriented teaching. So, you won’t find any PPTs during the sessions. But, you will find dozens of real time scenarios used to elaborate Java basic and advanced concepts.

Feel free to post your questions/feedback in the block provided under each session-video. I will make sure that all of your queries are addressed. ‘Course Outline’ below will give you a good idea about the depth and the overall coverage of this course. If you want to learn any other Core Java concept – which is not already covered in this course – then feel free to let me know via Udemy messenger.
