RandomNameRandomSynopsis
DescriptionThe Random class is a pseudorandom number generator. Pseudorandom numbers are generated by starting with a seed value and then using an algorithm to generate a sequence of numbers that appear to be random. The Random class uses a 48bit seed and a linear congruential algorithm to modify the seed. As a consequence of this implementation, two Random instances that are constructed with the same seed value generate exactly the same sequence of numbers. The Random class provides methods that return pseudorandom values for various primitive Java types. The Math.random() method is easier to use if you do not need to finetune the generation of random numbers. Class Summary
