Overkill is an understatement ;-)

More to the point, presumably you want to do this with the least possible fuss,
and I don't think there is anything simpler than either:

a) Encoding it as text in a string.  That assumes that the strings data itself
is not difficult to recognise and parse (quite possibly not true).

b) Encoding it binary in a byte[] array.  In that case you would have to
specify the size and byte order of the representations of the two integers
(say, 4-bytes, little-endian, unsigned).  And would have to specify the
encoding of the binary representation of the String data (say UTF-16LE,
preceded by a 32-bit length indicator).

Either is simple to implement, if you need further pointers ask again.
