Java random number SummaryRandom numbers are widely used in practice. For example, a fixed-length string or number
How to generate Java random numbers
In Java, the concept of random numbers in general, there are three kinds.1, through System.currenttimemillis () to obtain a current time of the number of milliseconds long number.2. Returns a double value from 0
One. In J2SE we can use the Math.random () method to produce a random number, the resulting random number is a double between 0-1, we can multiply him by a certain number, for example, multiplied by 100, he is a random within 100, this is not in the
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
