Random Number

Question

Is there any way to generate random numbers in any programming language without using functions like math.random or related function. I mean purely a block of statement to generate randoms

Answer 1

String charsCaps = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
String chars = "abcdefghijklmnopqrstuvwxyz";
String nums = "0123456789";
String symbols = "!@#$%^&*_=+-/€.?<>)";

String passSymbols = charsCaps + chars + nums + symbols;
Random rnd = new Random();

char[] password = new char[len];
int index = 0;
for (int i = 0; i < len; i++)
{
password[i] = passSymbols.charAt(rnd.nextInt(passSymbols.length()));

}
