Random Extension

An extension to the Random class to help convert the random number generator class to generate more than just integers. It is very simple to use, pass your array of random choices as parameters to the method.
Hint: Make your Random instance static so that the choice of random values is not continually reset back to the start.

private static Random random = new Random();

/// "Liverpool", "Southampton", "Manchester United", "Barcelona"
/// then use the following line:
