In Java to generate a random number, in fact, or after a complex algorithm,
He is usually through a generated by the current time (and some other conditions) seeds, to determine the random sequence of a cycle is large enough, in the selected random number
So, if you really have two exactly the same seed, the generated random Numbers may be the same,
But the chance is small to the extent to which we can ignore the, at this time we repeated the infinitesimal chance directly to use pseudo random number,
So it is not very special circumstances, the pseudo random is enough,,

So the real random number really can only throw the dice,

Is that the true random number refers to random Numbers are obtained by physical means such as the throw the dice, machine is difficult to do,

come out after you, and so on a quantum computer, it should be able to realize, after all, now the machine does not have physical random module like dice

Well that is now unable to achieve a true random number

Is this

Good , thank you for your answer
