Learn Java Streams and Lambdas

Dive into Functional Programming with Java

Learn Java Streams through Practical Coding

The introduction of functional interfaces and lambda expressions in Java 8 marked a fundamental shift for the language – incorporating the functional programming paradigm in Java. Also added in the same release, the Streams API relies on these for a concise, expressive syntax.

Unlike a Collection, a Stream is not a data structure, but a view over a data source. This sequence of elements supports operations that we can combine into a “stream pipeline”. Which opens up a number of new approaches. 

In this course, we’ll start by reviewing the core concepts of functional programming, the benefits and downsides of Streams, and how Streams and lambdas work together. Then, we’ll learn how to combine intermediate and terminal operations to process data. We’ll analyze each operation individually, as well as how to chain them effectively, while adhering to the principles of non-interference, statelessness, and non-reusability.

Actual coding practice through a Java project – definitely the best way to learn how to work with Streams and lambda expressions

The essential path to working with Streams and lambdas in Java, professionally. The 5 modules build a solid base of understanding how to effectively add functional programming to your toolkit and use it when appropriate.

Everything you need to understand the Java Streams API and be prepared for both in-depth Streams interview questions or going through the Oracle certification.
