| 8. JCSC | | By: | | | License: | GNU General Public License (GPL) | | URL: | http://jcsc.sourceforge.net/ | | Description: | 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, ... . JCSC is inspired by lint.

JarJarDiff is another important tool in the suite. It compares two versions of the same codebase and reports the differences in the API. It lists new, changed, and removed elements such as packages, classes, methods, and more. You can tailor the reports to focus on your public, published API versus the private, internal one.
Finally, Dependency Finder has a tool for computing object-oriented software metrics that give you an empirical quality assessment of your code. Once again, you can tailor the report to focus on the metrics that you care about and adjust validity thresholds to the specifics of your project.

| 14. Java PathFinder (JPF) | | By: | | | License: | Open source | | URL: | http://javapathfinder.sourceforge.net/ | | Description: | Java PathFinder (JPF) is a system to verify executable Java bytecode programs. In its basic form, it is a Java Virtual Machine (JVM) that is used as an explicit state software model checker, systematically exploring all potential execution paths of a program to find violations of properties like deadlocks or unhandled exceptions. Unlike traditional debuggers, JPF reports the entire execution path that leads to a defect. JPF is especially well-suited to finding hard-to-test concurrency defects in multithreaded programs.
While software model checking in theory sounds like a safe and robust verification method, reality shows that it does not scale well. To make it practical, a model checker has to employ flexible heuristics and state abstractions. JPF is unique in terms of its configurability and extensibility, and hence is a good platform to explore new ways to improve scalability.
JPF is a pure Java application that can be run either as a standalone command line tool, or embedded into systems like development environments. It was mostly developed - and is still used - at the NASA Ames Research Center. Started in 1999 as a feasibility study for software model checking, JPF has found its way into academia and industry, and has even helped detect defects in real spacecraft.
