Code Style

Introduction

We follow the Google Java Style Guide for our Java code. Here is a brief summary of the most important points:

General

• Spaces, not tabs
• No wildcard imports
• Column limit 100

Braces

• Always use braces, even when optional
• Use Egyptian brackets

Misc

• Always use @Override
• Use capital L in long literals

Vertical whitespace

• Must use one blank line between methods
• Can use blank line(s) to group fields
• Can use blank lines(s) to group statements
• Note: Don't use more than two consecutive blank lines

Horizontal whitespace

• Use a space between keywords and braces
• Use a space around binary or ternary operators
• After ,:; (unless it's a trailing space)

IDE settings

The repository has a .editorconfig with indentation settings that should be supported by most IDEs. If you are using IntelliJ IDEA, the config files in the .idea directory should already configure the defaults correctly to adhere to the code style by default. You can reformat code in a file by pressing cmd + alt + L.
