How to split filesystem path in Java?

Question

If I have a string variable inside one class

MainActivity.selectedFilePath

which has a value like this

/sdcard/images/mr.32.png

and I want to print somewhere only the path up to that folder without the filename

/sdcard/images/

Answer 1

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");

See it

Answer 2

    String string = "/sdcard/images/mr.32.png";
    int lastSlash = string.lastIndexOf("/");
    String result = string.substring(0, lastSlash);
    System.out.println(result);
