Question

I need to hash some strings so I can pass them into some libraries, this is straight forward using the String.hashCode call.

However once everything is processed I’d like to convert the integer generated from the hashCode back into the String value. I could obviously track the string and hashcode values somewhere else and do the conversion there, but I’m wondering is there anything in Java that will do this automatically.

Answer 1

I think you misunderstand the concept of a hash. A hash is a one way function. Worse, two strings might generate the same hash.

So no, it’s not possible.
