Random類和Math.radnom()方法的聯繫

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"></span><pre name="code" class="java"> public static double random() {
        Random rnd = randomNumberGenerator;
        if (rnd == null) rnd = initRNG();
        return rnd.nextDouble();
    }

math.Random方法底層實現使用了Random類。

 public static double random() {
        Random rnd = randomNumberGenerator;
        if (rnd == null) rnd = initRNG();
        return rnd.nextDouble();
    }
