Java filename from Path

Java filename from Path

In this tutorial we’re going to show how to get filename from Java 7 Path. The new, flexible API offers more choices to that.

Filename from Path using Path.getFileName()

This is the simplest way to obtain filename from Path:

Path path = Paths.get("/proc/version");
System.out.println("path.getFileName(): "
    + path.getFileName().toString());

The above code produces:

path.getFileName(): version

Taking filename using Path.getName()

In this approach we can get any part of path, including filename:

Path path = Paths.get("/proc/version");
System.out.println("number of name parts: " + path.getNameCount());
System.out.println("path.getName(0): " + path.getName(0));
System.out.println("path.getName(1): " + path.getName(1));

It gives the following output:

number of name parts: 2
path.getName(0): proc
path.getName(1): version

Note: remove redundant elements from Path before getting its parts!
