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.

Passionate about programming computers for over 20 years, Jose made his debut in assembler and C, C for SIMD parallel machines before adopting Java as an object-oriented language, indispensable to most major modern applications. He brings his expertise and capacity for analysis and synthesis to many projects, mainly in the lower layers, close to the data, but also on complex UI design, or in the browser.
