    {
        // creating and initializing Bidi
        // with base direction
        Bidi bidi = new Bidi("Tajmahal", 0);
  
        int index = 0;
  
        // getting the start of run for the index 0
        // using getRunStart() method
        int level = bidi.getRunStart(index);
  
        // display the result
        System.out.println(
            "start of run for index 0 is : "
            + level);
