Finding relationship between java classes

Question

I would like to create a graph which contains Java classes of a program as nodes and the relationships between the classes as edges. How can I determine the relationships between classes? I thought about checking the import statements, but they are often inaccurate because of the * wildcard.

Answer 1

You are going to need a compiler.

Or look at compiled code.

Easiest kludgey way: Load the code and apply java.lang.reflect (or a library which uses that).

The difficult way: Read the class files. Probably use one of the libraries which handles this.
