This value is different every time the method is invoked. However the concurrent use of the same javautilRandom instance across threads may encounter contention and consequent poor performance. Instances of javautilRandom are threadsafe.
When this method is first called it creates a single new pseudorandom-number generator exactly as if by the expression new javautilRandom.
It cannot be chosen or reset by the user. 1 public static double random This method returns a double number greater than or equal to 00 and less than 10 Note that the 00 is inclusive while 10 is exclusive so that 0. Instances of javautilRandom are threadsafe. You only want a random number between 0 and 100 you can use the following formula.
