Steve: Tick.gif Does work, but output only viewable in any legable format within the application itself - more suited to individual use.
ZbbFufu: Tick.gif Can also be used as ant task to output html reports. Good reports for continuous integration.
QJ-Pro is a comprehensive software inspection tool targeted towards the software developer. Developers can automatically inspect their Java source code and improve their Java programming skills as they write their programs. QJ-Pro provides descriptive Java patterns explaining error prone code constructs and providing solutions for it.
Steve: Cross.gif Not been updated for 9 months, does not work on Java 1.5.
Hammurapi is an open source code inspection tool. Its release comes with more than 100 inspectors which inspect different aspects of code: Compliance with EJB specification, threading issues, coding standards, and much more.
Steve: Question.gif Only analyses comments and documentation within the code.
Condenser is a tool for finding and removing duplicated Java code. Unlike tools that only locate duplicated code, the aim of Condenser is to also automatically remove duplicated code where it is safe to do so.
JCSC is a powerful tool to check source code against a highly definable coding standard and potential bad code. The standard covers naming conventions for class, interfaces, fields, parameter, ... . Also the structural layout of the type (class/interface) can be defined. Like where to place fields, either before or after the methods and in which order. The order can be defined through the visibility or by type (instance, class, constant). The same is applicable for methods. Each of those rules is highly customizable. Readability is enhanced by defining where to put white spaces in the code and when to use braces. The existence of correct JavaDoc can be enforced and various levels. Apart from that, it finds weaknesses in the the code -- potential bugs -- like empty catch/finally block, switch without default, throwing of type 'Exception', slow code, ...

JDepend traverses Java class file directories and generates design quality metrics for each Java package. JDepend allows you to automatically measure the quality of a design in terms of its extensibility, reusability, and maintainability to effectively manage and control package dependencies.
Steve: Question.gif Only finds dependencies within the code.
Checkstyle is a development tool to help programmers write Java code that adheres to a coding standard. It automates the process of checking Java code to spare humans of this boring (but important) task. This makes it ideal for projects that want to enforce a coding standard. Checkstyle is highly configurable and can be made to support almost any coding standard. An example configuration file is supplied supporting the Sun Code Conventions. As well, other sample configuration files are supplied for other well known conventions. Can be integrated into CruiseControl and Eclipse.
Steve: Question.gif Only checks that code conforms to their coding standard.
Classycle's Analyser analyses the static class and package dependencies in Java applications or libraries. It is especially helpful for finding cyclic dependencies between classes or packages. Classycle's Dependency Checker searchs for unwanted class dependencies described in a dependency definition file. Dependency checking helps to monitor whether certain architectural constrains (e.g. in a layered architecture) are fulfilled or not.
