Android : How to display date in exact format with month and year format

Hi how to display given string with July 3, 1969 for string 1969-07-03

String a="1969-07-1969;

Expected output: July 3, 1969

I used this method initially to convert in right format.

  textView.setText(reverseIt(a)); // but this reverse the whole string.

    public static String reverseIt(String source) {
        int i, len = source.length();
        StringBuffer dest = new StringBuffer(len);

        for (i = (len - 1); i >= 0; i--)
          dest.append(source.charAt(i));
        return dest.toString();
      }

Please help me to solve this.
