Class org.apache.commons.math.random.RandomData

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

org.apache.commons.math.random.RandomData.nextInt()
Generates a uniformly distributed random integer between lower and upper (endpoints included).
The generated integer will be random, but not cryptographically secure. To generate cryptographically secure integer sequences, use nextSecureInt.

Preconditions:
- lower < upper (otherwise an IllegalArgumentException is thrown.)
@param lower lower bound for generated integer @param upper upper bound for generated integer @return a random integer greater than or equal to lowerand less than or equal to upper.
