What you'll learn

Lambda Expressions are one of the foundations of the Java language since Java 8, but it can be a bit tricky. In this course, Using Java Lambda Expressions, you will learn how to write these expressions in a simple method that will never fail. First, you will see how to write lambda expressions using a simple method that you can use in any kind of situation. Then, you will learn how to chain and compose lambdas, leveraging the default methods from the interfaces these lambdas are implementing.
