i think intellij idea (http://www.intellij.com/, free fully functional
trial available) could help you a lot with its inspection feature..
there are also some plugins available for "more improved inspection"..

however, it's not a command line solution..

regards,

daniel

Here's the teaser blurb: PMD scans Java source code and looks for potential problems like: * Unused local variables * Empty catch blocks * Unused parameters * Empty 'if' statements * Duplicate import statements * Unused private methods * Classes which could be Singletons * Short/long variable and method names __________________________________ Do you Yahoo!?

Did you check the Java compiler options? The latest build 3.0M6 can even give you warnings for bad Javadoc, as well as undocumented empty blocks, arguments hiding members, unused private methods, unread members and variables, and so on.

Re: Java code inspection tools

Checkstyle will find unused imports, unused variables, flag methods without javadocs, or javadocs that don't have parameter lists that match the method signature. It also is great at enforcing coding conventions. http://checkstyle.sourceforge.net JDepend analyzes class files and will tel you dependencies on other packages. It also generates metrics about abstractness and stability of packages. Theoretical stuff, but very useful. There is a good article on it at http://www.onjava.com/pub/a/onjava/2004/01/21/jdepend.html JavaNCSS is a tool for measuring the number of non-commenting source code lines per package, class, and method. It also generates some metrics about individual methods (McCabe's Cyclic Complexity Number). Again, theoretical, but useful for detecting code that 'smells' bad. http://www.kclee.com/clemens/java/javancss/ Macker is a atchitectural rule checking utility for Java. My project uses it to set up rules such as 'the swing client package cannot directly use our enterprise java bean package'. http://innig.net/macker/ PMD is a tool for scanning java source and looks for things like swallowed exceptions, unused methods & variables, etc. It has similar capabilities to Macker, but they have slightly different flavors. http://pmd.sourceforge.net/ On my project, we use all of these tools to produce html documentation (along with javadoc, and some custom tag docs with xDoclet). With most on these tools, they generate an XML report that is transformed into HTML... I've been wanting to research making a stylesheet that would take all these different metrics and create a single report for each class or package, rather than a report from each tool. If anyone has such a thing, I'd like to know about it. -db On Mon, 2004-01-26 at 09:32, Jorquera, Lorenzo wrote: > Hi everybody!! > > I have to evaluate some Java code written by somebody else and I am > wondering what tools are available to inspect Java code.
