If I have a string variable inside one class

MainActivity.selectedFilePath

which has a value like this

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

/sdcard/images/

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);

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

  • Files

If the Files actually exist on the box, you could wrap the Strings up in a File object and call File.getParent().

  • String.split()

If the files don't exist, you could use the String.split() function to split the String with "/" as delimiter. You could then drop the last String in the array and rebuild it. This approach is rather dirty though.

  • Regular expressions

You could use regular expressions to replace the part after the last / with "".

Here is the solution - 

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

try this :

File file = new File("path");

parentPath = file.getParent();

parentDir = file.getParentFile();

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

Check out Apache FileNameUtils in the Apache Commons IO library, and in particular getFullPath().

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

You can use String.lastIndexOf(int ch); which gives you the last occurrense of the character ch

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