This week we will take a look at lambda expressions. We will take a look at some basics, show some of the standard functional interfaces, show how lambdas can be used with Streams and at the end it is shown how method references can be used. After reading this, you will have some basic knowledge of lambda expressions. The examples can be found at GitHub in the repository https://github.com/mydeveloperplanet/mylambdaplanet
In this second post about Java 9, we will focus on changes in the Collections and Streams API in the Java language. Examples can be downloaded via the following git repository: https://github.com/mydeveloperplanet/myjava9planet . The examples in the post below can be executed with JShell, the examples on GitHub contain the examples with unit tests.
The first post in the series of Java 9, which I announced a few weeks ago, will be about JShell. JShell is the REPL (Read-Eval-Print loop) tool for the Java language. The tool allows you to test snippets of code outside of your IDE. In this introduction, we will explore some of the features of JShell.
