Lambda expressions (also known as closures) are one of the most anticipated and popular new features released by Java8. It can greatly replace the use of anonymous inner classes, simplifying the code and highlighting the most important part of the original anonymous inner classes that contains real logic.

For students learning big data, when you get used to using functional programming languages like Scala, you will find the terrible thing about Lambda-doing what the previous class did with very little code!

Some students worry that it is difficult to learn Lambda, in fact, you just did not find the right way. Next, the editor will share with you a great tutorial to let you learn Lambda expressions in 2 days is not a dream!
