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!
