Course Overview:
This course has been developed to just not teach core Java skills, but with a larger goal of helping you become a complete & professional Java engineer right by the end of this course. To realize this, it takes a holistic approach in teaching Java programming. To ensure that you master Java language, the course has been developed to be highly comprehensive covering most of the Java language features and discussing them at a very in-depth level. To further ensure you are industry-ready and can write well-designed, professional code, tons of best practices & design principles are explained and demonstrated in code. Towards this end, you'll also implement an instructor-led Java EE Web application using professional coding conventions with Eclipse as IDE. Finally, all your questions will receive in-depth personalized responses within around 24 hours.

Course Specifics:
This course begins by giving a birds-eye view of Java covering everything from origin of Java to installing Java and writing your first Java program. Even the most fundamental concepts like compilation & interpretation are explained. All other topics are covered in-depth starting from language basics, object-oriented concepts & design, JVM internals, exceptions, IO, collections framework, generics, multi-threading, databases, nested classes, enums, and functional-style programming via Java 8 constructs like lambdas & streams. You'll also learn about database designing, implementation (SQL), and how to interact with them from Java programs (via JDBC). The course also gives a very good introduction to Java EE technologies like JSP, Servlets and JSTL, which help in project implementation. Finally, an excellent Eclipse IDE tutorial is also included, which teaches you how to use Eclipse professionally for effectively writing, debugging and even testing Java programs using the JUnit framework.
Each lecture has been very carefully crafted explaining the motivation behind every concept. Each concept is clearly explained with well thought out examples & illustrations and is demonstrated in code. Object-oriented concepts like inheritance & polymorphism are explained through a real-world case-study, which is also implemented as part of the course project. Several challenging coding exercises & quizzes are included to reinforce what you've learned. Your solutions for coding exercises are also auto-evaluated to help you instantly know whether or not the solution is correct.
The course project involves building a bookmarking Web application that helps users bookmark items like Books, Movies, and Web pages and is built progressively as new concepts are learned. The project is instructor-led and is implemented using professional coding conventions & best practices. It follows good object-oriented design, incorporates MVC architectural pattern and also uses Test-Driven Development (TDD) methodology. Java EE stack comprising technologies like Servlets, JSP, and JSTL are used for building the application with MySQL as the database and Apache Tomcat as the Web server. Parts of the project use advanced multi-threading capabilities.
Finally, course also teaches several best practices & design principles that are essential for writing well-

To be honest, this course covers all the topics of Core Java. The low rating is because of the narrow mindedness of the author.I have purchased many courses by people like Maximilian, Brad Traversy, Andrew Mead . These people implement multiple projects in their courses and they give the source code for the projects. So that their students can cross check the code, when they get any error.This author implements two basic projects, but he doesn't even give the complete source code as a downloadable zip, because he thinks that others will copy these simple projects. Even every slide starts with a warning to not distribute these slides. This is the first time i am seeing such things in a Udemy project.The author seems to be paranoid that other people will copy his code or use his slides.

Amazing instructor, very detailed course for serious learning; no superficial content at all; the course is very well organized, we really feel that a lot of time investment was done to prepare this course. Also, when there is question, the instructor/ or TA are quick to respondI recommend this courseThanks Dheeru

Instructor is highly knowledgeable and experienced. He has in dept knowledge of concepts also very responsive if you ask any doubts but this course is not for beginners.

I have done it 100%!! God!! this is the most thorough course I have ever seen! Before I started this course I used to boost myself as I knew Java, but believe me I hadn't even known 0.001 % of it.This course takes you from the most basic to the most Comprehensive aspect of Java. The Instructor is not merely a an instructor, rather seems creator of Java itself! He has very good knowledge and being learnt buy such Instructor gives no chance for misunderstanding.I would rate this course 6.0 point, but I got the following issues to do that:1) The maximum rating is 5.0 .... Oopsss :(2) I am tired of writing notes, because I didn't want to miss any of his explanation. So valuable!! Would have been excellent if at least kind of summary notes was available for download.However 5.0 rating is a must and I gave it!Thank you so mach for the in depth course!!! Loved it!!!Moving the control to the next java course towards fullstack lol! :)

Its really an excellent course to get the good knowledge on Java. Basic concepts are explained clearly. I suggest everyone who is going to start their Java world.

Little hard to understand the speaker, but once you get used to that, this class is WAY better than any "perfectly organized" class I've studied... He really took the time to make sure you understand a concept before the next concept is introduced (which is hard sometimes... you have to skirt around using terms not yet introduced). Everything is well laid out and he gives reference to his real-world experience on very important points. This is helping me find the most important data out of the sea of data out there. I hope to update this review when I really get busy programming, and can say whether the data really is correct. But at half-way mark, everything seems to just make sense. I even recently spotted the root cause of some programming errors in a major app, and confirmed my suspicions by reviewing Apple's release notes to developers... different language, but shows this teacher made sure I understood the very fundamentals!

An excellent course - thorough, persistent, teaches both via theory and example. One of the best courses I took on this site.

Very detailed. Not just videos has many assignments and resources to work with. Extremely useful, highly recommended.

This is the most comprehensive course on Java you will find. It's more valuable than the 2 courses I took in college on Java.Dheeru covers everything and was quick to clear up any confusions.This is by far the best course I've taken on UdemyThis course should be the standard by which you judge other courses. Excellent work Dheeru!

It is a wonderful course, very informative. I just loved the way it was presented. All the resources were helpful. The tutor is awesome and is very helpful.

This course is very detail and well-organized. It's very worth to take a chance of it! :)

It's a fantastic course for the people who want to learn java from scratch to advance level. I would like to thank the instructor for providing such detailed information about java from basics to advance. I'm glad to be a part of this course.
