    This program shows how some common Kotlin String methods work.

      - indexOf() returns the index of the first occurrence of a substring
      - lastIndexOf() retruns the index of the last occurrence of a substring
      - substring() returns the specified substring
      - replace() replaces all occurrences of a substring
      - toUpperCase() returns a string in which all letters are converted
        to upper case if necessary.
