Loading classes from a set of files

I have a task to check a set of conditions for unknown set of classes from classpath. I want to scan it for classes, load each of them and perform my checks. Now I have a set of urls to class files and I try to use URLClassLoader. But to load a class I need to specify a fully qualified class name, but I don't have them (I have only file path). I don't think that building class name from class file path is relieble, is it a better way to do it?

Thanks!

Solution

  • I'd just parse the beginning of the class file, looking for "package" keyword and first occurrence of "class" keyword. Then, when you combine those two (packageName + "." + className), it should result in a proper class name.
