Java – a tool for generating graphical data for class dependencies

Are there any tools that can analyze java source files, build graphics from them, and provide graphics data in some standard / understandable format?

It absolutely doesn't need GUI. I prefer command-line things, so I can deal with various tools for output (segmentation, visualization,...)

Solution

I'm not sure about command line tools, but I like to reverse engineer objectaid into class diagrams:

http://www.objectaid.com/

You can easily add any class and its relationship to the objectaid diagram It uses the ucls extension to save the file in XML format Here is an example:

You can also use plantuml, but reverse engineering is better than reverse engineering:

http://plantuml.sourceforge.net/

Plantuml has its own unique syntax, and you can get the source code, but it is not as simple as objectaid

Both are eclipse plug-ins. Sorry, I don't know more about any command line tool that may do what you require
