Question

I want to list all files with a specific name in the class path. I am expecting multiple occurrences, hence Class.getResource(String) will not work.

Basically I have to identify all files with a specific name (ex: xyz.properties) anywhere in the class path and then read the metadata in them cumulatively.

I want something of the effect Collection<URL> Class.getResources(String) but could not find anything similar.

PS: I don’t have the luxury of using any third party libraries, hence in need of a home grown solution.

Answer 1

You can use Enumeration getResources(String name) on the class loader to achieve the same.

For example:

Enumeration<URL> enumer = Thread.currentThread().getContextClassLoader().getResources("/Path/To/xyz.properties");
while (enumer.hasMoreElements()) {
    System.out.print(enumer.nextElement());
}
