[JAVA] Reduce verbose code with Lombok

What is Lombok

Lombok is a library that simplifies boilerplate such as Java getters / setters. Just annotate the field methods and they will automatically generate the code at compile time. You don't have to do the automatic generation in the IDE, which you would have done so far, and you can also reduce change mistakes. Click here for GitHub.

Operating environment

Introduction

1. From the menu, click Android Studio → Preferences ... → Plugins → Browse repositories ...

2. Search for "lombok" and select "Lombok Plugin"
