This paper mainly introduces 3 kinds of methods of obtaining random number in Java, mainly using random () function to realize
Method 1

almost all programming languages provide a "generate a random number" method, that is, call this method will generate a number, we do not know in advance what the number it generates. For example, in. NET, write the following code:

In a real sense, random numbers (or random events) are randomly generated based on the distribution probability shown in the experiment process. The results are unpredictable, is invisible. The Random Functions in the computer are simulated
How to generate random numbers in C/s + +: The rand () function, the Srand () function, and the random (int number) function in the C language/c++ are used here. (1) If you want to generate random numbers without setting the range, you can just use
Random numbers are often used in actual development work. When a user is created in some systems, a random initialization password is given to the user. This password because it is random, so often only users know. After they have acquired this
