Coding Guidelines

This is a small overview of guidelines regarding new and changed code.

Code style and conventions

All new and changed code must adhere to the Java Code Conventions from Oracle or the Google Java Style Guide.
We reserve to be lenient with existing code and arbitrary restrictions regarding row and column counts.

Use your IDE's formatter liberally and regularly. A code style file for IntelliJ exists and matches our preferred style.

Do's and Don'ts

Modern Language Feature	High	Use functional built-in types for lambdas and functional expressions instead of custom counterparts. There are numerous classes that have direct built-in variants in Java	Use Consumer<T> instead of Runnabled<T>
