1. Change the method name corresponding to the server method on the clientDuring development, you may encounter the following problem: the server exposes two methods, one of which is to overload the other. That is, the two methods have the same name,

Java implements random and non-repeated numbers. Generally, developers with some development experience can achieve this function, but it is only a matter of efficiency. In general, when we are faced with such a problem, we will always think of it

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
