<p>substring()
    has two forms.</p>

    <p>The first
    takes the
    index to
    start with
    and the
    index to
    stop immediately before.</p>

    <p>The second
    takes just
    the index
    to start
    with and
    goes to
    the end
    of the String.</p>

    <p>indexes are
    zero based.</p>

    <p>The first
    call starts
    at index 1
    and ends
    with index 2
    since it
    needs to
    stop before index 3.</p>

    <p>
    The second
    call starts
    at index 7
    and ends
    in the
    same place, resulting
    in an
    empty String.
    This prints
    out a
    blank line.</p>

    <p>The
    final call starts
    at index 7
    and goes
    to the
    end of
    the String.</p>
