Using Java Lambda Expressions from Pluralsight

Lambda Expressions are one of the foundation of the Java language available since Java 8. In this course, you will learn a very simple method to write lambda expressions that always works and how to chain and compose them.

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. Finally, you will hear about performances and see how to avoid performance hits by using specialized lambdas. By the end of this course, you will be able to write suppliers, consumers, predicates and functions: the four fundamental interfaces from the java.util.function toolbox.
