How do I get the file name from a String containing the Absolute file path?

String variable contains a file name, C:\Hello\AnotherFolder\The File Name.PDF. How do I only get the file name The File Name.PDF as a String?

I planned to split the string, but that is not the optimal solution.

Solution 1:

just use File.getName()

File f = new File("C:\\Hello\\AnotherFolder\\The File Name.PDF");
System.out.println(f.getName());

using String methods:

  File f = new File("C:\\Hello\\AnotherFolder\\The File Name.PDF");  
System.out.println(f.getAbsolutePath().substring(f.getAbsolutePath().lastIndexOf("\\")+1));

Solution 2:

Alternative using Path (Java 7+):

Path p = Paths.get("C:\\Hello\\AnotherFolder\\The File Name.PDF");
String file = p.getFileName().toString();

Note that splitting the string on \\ is platform dependent as the file separator might vary. Path#getName takes care of that issue for you.
