Here’s an example from twitter’s style guide that makes good use of this concept: The general convention is to break after commas, before operators, and use a hint of common sense. Of course apart from natural breaks after semicolons, line breaks are used not only when lines get too long but also for logic separation.

The general convention is around 80-100 max length

Sometimes lines of Java code tend to get long, and the style guides set conventions on when is it appropriate to break or wrap. Java Tabs vs Spaces – Analyzing popular code conventions (Source: outsideris/popularconvention) 2. (In case you were curious, at OverOps we prefer tabs. BTW, peeking over to other JVM languages like Scala and Clojure, we see almost 100% 2 spaces.Ĭonsidering a larger dataset that covered individual commits gave us different results (The convention analysis project, one of the Github data challenge winners), but we can estimate it to be somewhere in-between probably closer to 10%. There’s actually a pretty nice module for running this analysis (comparing different languages). Perhaps developers who use tabs don’t like writing style guides ?ĭata from Github suggests that around 10-33% of the Java repositories prefer tabs, and the majority use spaces in different formations, preferring 4 spaces over 2. Java: 4 spaces, tabs must be set at 8 spaces. Google: 2 spaces (android is 4 spaces, and 8 for line wraps) We’ll not go into pros and cons here and just share the findings: There’s a clear preference for spaces over tabs in the style guides. Indentation: tabs vs spacesįirst, we need to get this off our chests before proceeding.

The full style guides are available right here: The twitter guidelines specify one exception and we tend to agree, “if the more ‘readable’ variant comes with perils or pitfalls, readability may be sacrificed”. And the best thing you can do for the next person who reads your code is to stick to conventions.Ī consistent style of writing not only helps create good looking code, but also makes it easier to understand. It’s almost certain that you will not be the only person to read the code that you write.

Readability is the main consideration here. Code quality is crucial, which is why OverOps analyzes your code at runtime to give you actionable insight about all errors and slowdowns – even those that don’t end up in the logs. Psst! Whether you use tabs or spaces, it’s what you write after them that counts. In this post we will highlight formatting guidelines and different Java coding styles in companies like Google, Twitter, Mozilla, the Java standard and our own teams at OverOps. If there were such a thing as developer team anthropology, style guidelines would probably be a major part of it. Yes, even if tab width changes between editors, and spaces tend to be more precise. When it comes down to coding styles, most choices are pretty arbitrary and depend on personal preference. In spite of the suggestive image above, we don’t want to commence any unnecessary holy wars. What are the most interesting highlights in popular Java code styles?
