check if file exists without allocating memory

Question

I need to check if a file exists without allocating memory for it. I just want to check that it exists, I am not interested in getting the content. Is there a simple way to achieve that?

Yes: use a search engine. Next time just try putting your question into google. Surprise. — GhostCat, May 21 '18 at 14:17

The java.io.File.exists() method allows you to do just that:

boolean fileExists = new File("path").exists();

Creating a File instance does not read its content on the disk.

I forgot to mention that the file is on a remote server. How would look the code in that case? Can I put the remote host in the path string? – Jesus Paradinas May 21 '18 at 18:46

@JesusParadinas Unless the remote server is mapped to a local drive, the File API is pretty much not going to help. What protocol are you using to connect to the remote server? – ernest_k May 21 '18 at 18:52
I have been told that the servers are mapped. I am not sure how to connect do you have any suggestion? – Jesus Paradinas May 21 '18 at 19:48

@JesusParadinas Then I suppose the code should work. Try it. – ernest_k May 22 '18 at 04:49
