Setting up our development environment

Before we start, we need to set up our development environment. Our development environment consists of the following four tools:

• JDK
• Build tool
• IDE 
• Docker

We will install JDK version 8.0. This version is fully supported in Spring Framework 5. We will present the steps to install Maven 3.3.9, the most famous build tool for Java development, and in the last part, we will show you some detailed instructions on how to install IntelliJ IDEA Community Edition. We will use Ubuntu 16.04, but you can use your favorite OS. The installation steps are easy.
