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/

Solution 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

Solution 2

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

Solution 3

Create a File object with that path and then use getPath method from File Class.

Solution 4

String realPath = "/sdcard/images/mr.32.png";
String myPath = realPath.substring(0, realPath.lastIndexOf("/") + 1);

Solution 5

final String dir = System.getProperty("user.dir");
String[] array = dir.split("[\\\\/]",-1) ;
String arrval="";

   for (int i=0 ;i<array.length;i++)
      {
        arrval=arrval+array[i];

      }
   System.out.println(arrval);

The file does not need to exist on the file system to call getParent().
