how to choose java nio vs io?

Question

As we had known, If we want to use traditional IO to construct server, it must block somewhere, so we had to use loop or one thread one socket mode, So nio seem it is better

Answer 1

A little late, but personally, I use NIO even for the regular "everyday" file handling. So, I use things like:

 1. if(Files.notExists(path)) { } 
 2. Files.createDirectory(path);
 3. Files.newInputStream(path) targetPath.resolve("somefile.txt");
 4. Files.newBufferedWriter(path, charset);
 5. DirectoryStream directoryStream = Files.newDirectoryStream(path);

and it works fine for me. I prefer Path instead of the old File because of methods like relativize or resolveSibling.

Doesn't strike me as more complicated than IO.
