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))

Random.next () returns nonnegative random numbers;
Random.next (INT) returns a nonnegative random number that is less than the specified maximum value
Random.next (int,int) returns a random number within a specified range, for example ( -100,0)
1. Basic functionsThe functions required to take random numbers in C language are:int rand (void);void Srand (unsigned int n);The rand () function and the Srand () function are declared in the header file Stdlib.h, so you must include the header
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:
Random

Random. Next () returns a non-negative Random number;
Random. Next (Int) returns a non-negative Random number less than the specified maximum.
Random. Next (
