The example in this lesson uses a little bit more coding. Let’s look at our files and examine each one in more detail.

Create the project

We start from our previously defined project template and add the required dependencies and classes.

  • If you want to work within the Educative platform, simply use the project we’ve created at the end of this lesson. If you choose to work locally, you will need to create a Maven project oauth2 as described in “Introduction to Window Shopping.*
