Examples of org.apache.commons.math.random.RandomDataImpl.nextInt()

org.apache.commons.math.random.RandomDataImpl.nextInt()
Generate a random int value uniformly distributed between lower and upper, inclusive. @param lower the lower bound. @param upper the upper bound. @return the random integer. @throws NumberIsTooLargeException if {@code lower >= upper}.
