A well known algorithm for generating uniformly distributed random values is the linear congruential algorithm. This algorithm generates random integer values that range over all the possible positive and negative values of the integer type. It uses the formula X(n+1) = ( m * X(n) + a ) mod d Where the Xi are the generated random values, m is a constant multiplier, a is a constant addend and d is a constant divisor, which is usually a very big number and relatively prime to m. A seed value kicks off the sequence. The formula relies on the fact that integer arithmetic does not overflow but wraps around.

probably you could suggest me better way to generate numbers, thank you.
The "correct" way to use the Random class is to instantiate it once (preferably using the no-arg constructor) and reuse the instance:
