No, there is no such method. The hash function is lossy.
When you think about it, the set of all possible strings is much larger than the set of all possible ints, making a two-way mapping impossible.
If it were possible to recover the string from its hash code, that would enable one to compress an arbitrary amount of data into a single
int, and then to be able to perfectly reconstruct it.
