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.

        int iterations = randomData.nextInt(100, 1000);

            eDA2.addElement( i );
