random for a series of random numbers??????
Using Math.random works well when you need to generate a single random number. If you need to generate a series of random numbers, you should create an instance of java.util.Random and invoke methods on that object to generate numbers.
我想让大家帮忙给俺个这样的例子，用java.util.Random中的哪些方法就可以产生一系列的随机数呢？？？
