I have just launched my first course on Udemy. The course is on Lambdas and Streams in Java.
It is a comprehensive course(18 hours) where I start from the basics and dive deep into Lambda Expressions and the Stream API.
I also cover several features introduced in Java 8 like default methods, Method References, the Optional API, Comparators, Collectors, flatMap, Parallel Streams, and many more concepts. Besides this, there are plenty of exercises (along with the solutions).
The entire first section is available for preview. You can find more details and enroll in the course by clicking on the following link –
I hope you take a look at it. I would be happy to hear from you about the same.
