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))
Method 1(Data Type) (minimum value + math. Random () * (maximum value-Minimum value + 1 ))Example:(INT) (1 + math. Random () * (10-1 + 1 ))INT-type numbers from 1 to 10Method 2Obtain Random NumberFor (INT I = 0; I {System. Out. println (INT) (1 +

Java random number SummaryRandom numbers are widely used in practice. For example, a fixed-length string or number
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
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
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
