Hi! I am unable to assess your problem because you have not speculated your
problem.

In your dilema section, you gave a suspection but not a problem. What is the
code like? Give us a sample or at least a hint. What is the problem like?
What did you observe? What is the incorrect output that surprised you?

So far it all sounds pretty all right to me. The String.split method does
give empty strings when encountering consecutive delimiters, and it should
bring you to what you would have expected.

As an alternative approach to delimiter, you can store each data item with
the first few characters indicating the length of the data. when you retore
the data from the text, use a loop, first read the length, then read the
subsequent text of that length, and repeat it again. But I suspect it will
only increase your work.
