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 class (Java. util)
The random algorithm implemented in the random class is pseudo-random, that is, random with rules. When a random algorithm is executed, the numbers of the origins of the random algorithm are called seed. A certain number is
Java's Random class, apirandom
In the actual project development process, some random numbers are often required, such as verification numbers during website login, or a certain effect must be achieved at a certain probability, for example, items in

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

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
Random Class (Java.util)The random algorithm implemented in the random class is pseudo-random, that is, random with rules. At random, the origin of the random algorithm is called the seed number (seed), the number of seeds on the basis of a certain

Random. Next () returns a non-negative Random number;
Random. Next (Int) returns a non-negative Random number less than the specified maximum.
Random. Next (Int, Int) returns a Random number within the
The random class is a class that is specifically used to generate a pseudo-random number, which provides two constructors, one with the default seed, and another that requires the programmer to display the seed that passes in a long integer. Unlike
1. the random function is not ansi c standard and cannot be compiled by GCC, Vc, or other compilers. You can use the rand function in C ++.1. The C ++ standard function library provides a random number generator Rand, which returns a pseudo random
