Question

I want to write a java code, where given a directory name, I should be able to get all the files starting with list (so something like list*) and read each file one by one (linewise), and do some processing .

What classes are available and recommended to read a directory. Is my option is to read all file names by File.list and then pick the ones which start with list..

Thanks

Answer 1

Well, the most central class would be File.

Besides that there are some classes that File‘s methods need (like FileFilter etc.)

You can also try and have a look at utility libraries like Apache Commons IO.
