Static code analysis tools are a set of tools that analyze the source code of an application while looking for potential errors. These tools, such as Checkstyle, PMD, or FindBugs, have a set of predefined rules of good practices and parse the source code looking for violations of these rules. The objective is to find errors or places that cause poor performance at an early stage, before they are executed in production. Programming languages usually offer such tools, and Java is not an exception. One of the tools that helps analyze Java code is FindBugs. It's an open source tool that includes a series of rules to analyze Java-concurrent code.

In this recipe, you will learn how to use this tool to analyze your Java-concurrent application.
