Recommended Code Style Tool?

Actually this question doesn’t make sense without clarifying what you need a static analysis tool for. Are you looking to avoid unnecessarily verbose code, enforce consistent code formatting, avoid security defects, check your code metrics, or what? All these tasks are solved with static analysis tools, and each of these tasks is handled by a different tool in the Java world.

At JetBrains, we don’t use any tools other than IntelliJ IDEA’s built-in inspections.
