"This is by far the best advanced as well as beginner course I have ever read/seen since Andre LaMothe quit writing." ~ Stephen Jonson

"I'm leaving this review a couple years after having completed this course. This is hands down the greatest online course I've ever taken. Extremely in-depth, extremely thorough, and Dheeru was always helpful when I asked questions. 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. Thank you Dheeru from a former student!" ~ Carlvin Sanon

"Absolutely amazing, complete and in depth course. I would recommend this course to everyone interested in Java and programming in general. Dheeru Mundluru is an exemplary and responsive instructor. He explains the concepts with such clarity and with examples that every thing makes perfect sense. When I started this course, I only had vague idea of programming and now after completing this course I have a solid foundation to build upon. I would certainly say that due to this course I have fell in love with Java language and its ecosystem." ~ Muhammad Arsal Abdullah

"... This one should be the best seller of all the other ... " ~ Brady Adams

"This is a wonderful course. The Instructor is highly competent. He is a world-class instructor ... Taking this course will definitely give you a tremendous appreciation for this great language." ~ Carrel d'Haiti

"I have bought so many courses but this course has been a game changer to me . It is in depth as the name says. It helped me pass a paid internship interview in a reputable company and now i am getting a job. Thank you so much Dheeru Mundluru for releasing such a great course. You deserve 5+" ~ Stephen

"... I have been a Java developer for 8 years and hold a Masters degree in Computer Science ... This is honestly the very best online Java video course on the market... wish I had have had a course like this when I first started" ~ Clive Stewart

"This is THE best course on Java on Udemy - Period! Dheeru is not only passionate about what he is coaching but also OBSESSIVE and covers every minute detail of the subject ... Most lessons have demos which Dheeru makes sure that they do work without any glitches. He is a genius coder ... Plus, he bases the course on the best practices from the book "Effective Java" which is great. ... Lastly, he uses an accurate and powerful English vocabulary I'm yet to see from other instructors. If you want to learn Java right from installing, configuring and all the way to mastering its advanced topics - look no further - you are at the right place => THIS - IS - IT !!!" ~ Richard Reddy

"The JVM internals section of this course itself is worth buying this course. Excellent teaching style." ~ Ryan Trang

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. Over 5000 questions have already been answered so far!

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-designed code. This is one of the highlights of the course and will make you truly complete!

Story behind Creating this Course:

The idea for building this Master Course has taken its roots during the instructor's (Dheeru Munduru) experience as a software engineer in Silicon Valley. After working for several years with many excellent engineers, Dheeru realized that sometimes the teams he worked with fell short of developing effective solutions. This led to several rounds of "code refactoring" resulting in loss of valuable time. This he realized was due to programming not being taught in the right way at most Universities & Colleges across the world. Students are mostly taught core programming language features without any emphasis on best practices or design rules required for writing well-designed code. Due to this, developers are often ill-equipped when they have to come up with good solutions for complex problems. This leads to some quick ad-hoc & incomplete learning, which often not only result in bad solutions, but also more importantly causes lot of stress on developer's part. This made Dheeru realize that a more holistic approach to teaching is needed where programming language features are taught along with best practices & design principles needed for building well-designed robust software. This course is a result of this realization and it has taken him over 5 years of full-time effort (considered equivalent to over a decade if working part-time) in developing it. He will continue to devote himself in building this course towards making it one of the best Java courses out there.
