Generating random 3 digit kength number with specific numbers. Need help!
hi all.
My question is what can I sue to create String with random 3 digit length number (let's say ID) but made of only specific numbers like 1 3 6 9 0. Can use here math.random ? or is there another way, easier way. Can somepone please enlighten me here?
Re: Generating random 3 digit kength number with specific numbers. Need help!
public static String RandomString(int[] digits, int length) {
Random r = new Random();
String str = "";
for(int i = 0; i < length; i++) {
int n = (int) (r.nextDouble()*digits.length);
str += digits[n];
}
return str;
}
