I am using SecureRandom
to generate a random numbers.
Does it make any difference with respect to predictability of next number generated if the SecureRandom
object is a singleton or a new object is created every time a random number is generated?
Singleton:
public RequestIdGenerator {
private static SecureRandom secureRandom = new SecureRandom();
public static int generateRequestId() {
secureRandom.nextInt(100_000_000);
}
}
vs.
New object for each time random number is generated:
public RequestIdGenerator {
public static int generateRequestId() {
new SecureRandom().nextInt(100_000_000);
}
}
This question arose after reading about this answer related to 'Predictability of Linear Congruential Generators'.
