It would've been great if there were upto java 17 version. Seems like the course is not updated for a very long time. Current version is Java25 and the course just contains the content upto java 11. Requesting the instructor to update the course with more updated versions of java and how we can utilize them in Selenium.

Amazing course! Awesome instructor! I was searching for a good gRPC course, and I got only few results, and only Vinoth's course matched my requirement. I was initially skeptical about buying it, and I had no other choice at that time. But, after I started with that course, I was really impressed by its content. That's how I came into this course, and I loved this too. I am very thankful to Vinoth for his great content.
By Siddharth Gupta on 7/4/2024
I have taken few courses from Vinoth including this one. I cannot be more happier. He covers each and every concept in details with some great examples related to Automation so that you can easily relate to how the following Java changes can be incorporated in Automation. A big thumbs up. A big shout out to Vinoth. Do keep on making such great courses.

The course was good , I used to fear before regarding what is java 8 and all but sir teaching made it very simple and with a lot of practice I was able to do some assignments by my own, my java 8 fear has gone, Only one issue was in question answer section sir replies but mostly I didn't get proper answer but then also amazing course, best course for java 8

I rarely write reviews, almost never. But this course is must have for anybody like me, who got missed with Stream&Lambda understanding as some point while learning Java. Teacher is VERY aimed for delivering the understanding to students: repeats same thing several times, tries to explain same thing different ways, uses simple examples and then moves to real use cases. So, i feel like every penny i spent for this course worths it (from my point of view) Just completed the entire course, so planning now to also check the SpringBoot + Selenium course from this teacher, and hopefully i won't be disappointed as well!
By Praveen Kumar on 2/8/2021
You Know, Vinod, U did magic in this course. Any Automation engineer who is facing difficulties in learning Java * feature and its Usages in testing, must buy this course. I have 11 Udemy courses in the last 4 years but this is one course which I enjoyed lots while learning and completed in just 2 weeks. Giving 4.5 stars because we need more practice section this course with real-time selenium test cases.

Clean and detailed explanation, a good amount of technical details without losing focus on the main goal of the course. Appreciated the amount of code being demo'd. Liked the assignments, it was fun solving them, not too easy nor too challenging. I strongly advise this course to all the people who don't have the chance to work with Java latest versions but want to stay up-to-date with new features.
By Amuthan Sakthivel on 6/5/2020
I will highly recommend this course to SDET who really want to explore all the Java 8 concepts in depth. The assignments were designed in such a way to try them the learned features. I have already purchased the new course springboot with cucumber! Vinoth Selvaraj can be super tutor soon in udemy. I would appreciate an detailed algos and DS course from you Vinoth. Keep making videos :)
By Gomathi Shankar on 5/7/2020
Content is good and covered from testing perspective. When i was working on assignment, i was able to approach/think the solution from the on Streams,Lambda perspective . It solved the purpose of what i was looking from this course.. Now i have to solve more problem or start implementing the take away from this course in my Test automation implementation along wit. Thanks Vinoth. I have purchased the other 2 Selenium+Docker , Design Patterns of yours. Looking forward for some more courses from your end related to . Do you have any other in pipeline ?
By Amit Jain on 12/25/2019
Every one should take up this course. Very well planned content with explanation. The test automation examples mapping with java 8 and above are really out of box, these can really help in excelling testers to migrate there frameworks to java 8 and above. The trainer teaching style is very good. Sound knowledge of java and test automation. Looking forward for more courses related to testing from the trainer.
