Hi,

I have a requirement for generating reversible String to Number Conversion utility. Can somebody supply me the pointers to go about bulding this.

I am stating an example to clarify the need:

For input String 'Java Ranch' I need to generate a unique number which should be able to convert back to 'Java Ranch' string.

TIA,
Vijay

My guess would be HashMap.

Well, it all depends on how much you would like to complicate it. One simple way would be to get bytes from the String and convert them to a number, and then conver the number back to bytes and get the String, provided that you can use the same encoding for both operations all the time.



Anohter way could be encryption. See Java Almanac for an example.
