The random algorithm implemented in the random class is pseudo-random, that is, random with rules. When a random algorithm is executed, the numbers of the origins of the random algorithm are called seed. A certain number is
One. In J2SE we can use the Math.random () method to produce a random number, the resulting random number is a double between 0-1, we can multiply him by a certain number, for example, multiplied by 100, he is a random within 100, this is not in the
