how to get random number

This paper mainly introduces 3 kinds of methods of obtaining random number in Java, mainly using random () function to realize Method 1 (data type) (Minimum +math.random () * (maximum-min +1)) Example: (int) (1+math.random () * (10-1+1))

This article mainly introduces PHP's pseudo-random number and real random number details. This article first explains the concepts related to the real random number and pseudo-random number, and gives the comparison using mt_rand () an example code

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

In Java we can use the Java.util.Random class to produce a random number generator. It has two forms of constructors, each of which is random () and random (long Seed). Random () uses the current time, System.currenttimemillis () as the seed of the
