How to split file system path in Java?

If I have a string variable inside one class

MainActivity.selectedFilePath

which matters

/sdcard/images/mr.32.png

and I want to print somewhere only the path to this folder without a file name

/sdcard/images/

You can do:

File theFile = new File("/sdcard/images/mr.32.png");
String parent = theFile.getParent();

Or (less recommended)

String path = "/sdcard/images/mr.32.png";
String parent = path.replaceAll("^(.*)/.*?$","$1");

Take a look
