Re: file i/o with ArrayList

Hi Stefan,

for your use case (save and load at server start/stop) I'd recommend the
Kryo library.  It will store your data as a binary. Should be only two
lines of code each to persist and load the data.

You are right, writing is not very well developed, but then there are so
many utility libraries in Java that can be used for efficient
serialization/deserialization in many ways, once you have an object in
memory.
