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

Method One: Generate a random number between 0~nfunction Getrandom (n) {Return Math.floor (Math.random () * n);}Alert (Getrandom (10));Method Two: Generate a random number between the custom Min~maxfunction Getrandomnum (Min,max){var Range = max-min;
Java Random class is located under the Java.util package, mainly used to generate random numbers, this article explains the use of the random class, I hope to help everyoneRandom Class (Java.util)The random algorithm implemented in the random class
The methods provided by the Java.lang.Math class are static, and " static ingestion " makes it unnecessary to write the class name before the method every time the class method is called:import static java.lang.math.*;This allows you to simply write
Simulation algorithm: Simulate the whole process, by changing the mathematical model of the various parameters, and then observe the change of these parameters caused by the process state changes.Algorithmic thinking: Use random functions to

Language generation random number is a common programming function task, of course, this is not difficult, call two or three functions come out, but you know how these functions specifically play a role, and how they produce random numbers?
Several
Let me first introduce you to some related functions of random numbers:var Rand = Math.random ();
1.math.random (); The result is a random number between 0-1 (including 0, excluding 1)
2.math.floor (num); Parameter num is a numeric value,

Round-rounding floating point numbers. The round function syntax is as follows:
Round (float,precision)
Where the parameter precision represents the number of precision digits to be persisted after the decimal point. If the parameter
