Developers can action the warning messages in this Java code review tool either individually or in batches. FindBugs identifies inconsistencies as warnings, allowing the developer the discretion to review the messages to determine whether they need to take corrective action. Also a static analyzer, this tool scans the code to find defects (or 'bugs'), inconsistencies, or security threats in suspicious code sections. FindBugs/SpotBugsĪnother free and open source Java code review tool is FindBugs.

That’s why the tool also has a copy-paste detector called CPD that supports Java, Python, MATLAB, Fortran, C, C++, and C#, among others. PMD can also detect hard-coded IP addresses or passwords that could compromise security.Įliminating duplicate code within the Java application allows the code to run faster and offers a secondary check for manual reviewers who may have added redundant code sections. It reports common mistakes that reduce the code's efficiency, such as duplicate or unneeded code sections or variables and unnecessary objects. This Java review tool evaluates the integrity of the source code. PMD is a free, open source, static code reviewer that runs through Github.

The software generates reports that help proactively guard against unplanned code errors. In addition to those features, JArchitect can also identify code metrics like cyclomatic complexity (number of possible execution paths), source code lines, afferent (incoming) and efferent (outgoing) coupling, nesting, and depth. The tool also provides standard metrics and statistical analysis of the code. It offers features such as code querying, enabling custom code, technical debt evaluations to identify the cost of fixing – or risk of not fixing – an error, and pass/fail quality gates. JArchitect, a static Java source code analysis tool, evaluates Java code for complexity. With that in mind, here are seven Java code review tools that deliver on these critical benefits: While there are many Java code review tools available, we chose the list of tools below because they’re open source, easy to use, and are compatible with Java applications. Check out our set of best practices for your code review process. In addition, static code reviewers can augment manual peer reviews to create a robust process for streamlining code optimization. With so many development teams still recognizing these benefits and selecting Java, there’s a pressing need for powerful Java review tools to ensure secure Java code.Īutomated code reviews can improve the quality of software significantly, while also bolstering its resistance to security threats. The language’s demand stems from the platform being easy to learn with an extensive collection of APIs. It’s been more than 25 years since Java was created, but it is still one of the most popular languages for modern software development.
