Analysis and structure of Java code using a tool or pluggin

Question

Is there any tool to help analyze the structure of the code in a java project, either as an eclipse or as a separate one? I think something similar to what Structure101 seems to do, but I'm looking for something for free.
That is, to visualize the dependencies between jars, classes, class hierarchies, etc.
Basically, it’s better to understand the existing code base faster than setting encoding rules or a profile, etc.

Answer 1

I found the following useful tools

• CodePro Analytics - http://code.google.com/javadevtools/codepro/doc/index.html
• JDepend - http://www.clarkware.com/software/JDepend.html
• Sonar - http://www.sonarsource.org/
• Indicators - http://metrics.sourceforge.net/

Answer 2

do you mean sonar ?

Answer 3

Tons of them. The fact is that you probably want google for different tests, for example, "McCabe complex java" or "test coverage java".

You can take a look at this wikipedia article .

Update

Yeah. Try depfind .
