java - How to represent a 5 letter string as digit? -

i want create numerical representation of 5 letter codes. codes may have 1-5 letters or digits.

the number must of course unique. not absolutely necessairy numbers can converted ascii.

thus need digits 0 zzzzz

the resulting number size should small possible.

i started following, it's not quite want:

string a="zzzzzz"; (int = 0; < a.length(); ++i) {    system.out.print(a.charat(i)-'a'+1); }  zzzzzz=262626262626 000000=-16-16-16-16-16-16

start enumerating possible "digits" of number:

you have 36 possible "digits" 5 positions, max number 36⁵=60,466,176. number fits in int.

you can make number calling integer.parseint, , passing radix of 36:

system.out.println(integer.parseint("abzxy", 36)); // 17355958
