What you'll learn
Lambda expressions have been part of Java since Java 8 in 2014. In this course, Java SE Deep Dive: Lambda Expressions, you'll learn how to write and use lambda expressions in all the situations you will come across when working on your application. First, you'll see how lambda expressions are built and what their type is. Next, you'll discover how to chain them and to compose them. Finally, you'll learn how to use them efficiently to improve the quality of your code. When you're finished with this course, you will be able to write lambda expressions and method references easily, by just seeing the type of the lambda you need, and you will be able to refactor your existing code using lambda expressions to improve its readability.
