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

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
The random class is a class that generates pseudo-random numbers. Its constructor has two types: new random () and new random (int32 ), the former generates a random number based on the system time at which the trigger is triggered. The latter can
7 methods for generating random numbers in shell instancesI. Problems
A random number is sometimes used in Shell, and the method for generating the random number is summarized here. Computers generate only pseudo-random numbers and do not generate

First, the questionIt is sometimes necessary to use random numbers under the shell to summarize the method of generating random numbers. The computer produces only "pseudo-random numbers" and does not produce absolute random numbers (which is an
