Files searching in Java

Question

Because I asked wrong question last time, I want to correct my intention. How can I find file by name in specified folder? I have a variable with a name of this file and i want to find it in specified folder. Any ideas?

Maybe the simplest thing that works is:

String dirPath = "path/to/directory";
String fileName = "foo.txt";
boolean fileExistsInDir = new File( dirPath, fileName ).exists();

File is just a placeholder for a location in the file system. The location does not have to exist.

This is cool - it's funny I didn't think of it earlier. However, this approach won't work if you need to search recursively. – AbdullahC Nov 12 '11 at 18:01
Sure, recursive searching is more involved. The question does state "find by name in specified folder" though. – jackrabbit Nov 12 '11 at 18:08
"find by name in specified folder" reminds me of the Unix `find /folder -name 'file_name'` ;) – AbdullahC Nov 12 '11 at 18:11
Indeed, but doing that correctly from Java would be a lot of work :) – jackrabbit Nov 12 '11 at 18:34

Use Finding files in Java as a starting point. It should have everything that you are looking for - ask another specific question if you get stuck.
