    This course is very good for people who are new to JAVA 8 and also for people who want to brush up their JAVA 8. Segregation of topics is done in an awesome manner. Learning content is also very well described.
    If only I could give, would have given 10/10 rating to it.

    This is a very good course even if you have experience with Java 8 features. It was useful for me to practice more, especially with Streams and I’m very grateful to Dilip for this course. Now I’m taking his other one about Multithreading and it’s the same quality.

    I really enjoyed this course – I followed along with the lessons and practiced the functionality taught. At the end of the course I am now quite a bit more proficient in the Java Functional Programming style than I was before. Great course – it will really help you level up if you practice the material. Thank you 🙂
