import java.util.Random;
public class RandomRange {
// Declare as class variable so that it is not re-seeded every call
private static Random random = new Random();
/**
* Returns a psuedo-random number between Min and Max (both inclusive)
* @param min Minimim value
* @param max Maximim value. Must be greater than min.
* @return Integer between min and max (both inclusive)
* @see java.util.Random#nextInt(int)
*/
public static int nextInt(int min, int max) {
// nextInt is normally exclusive of the top value,
// so add 1 to make it inclusive
return random.nextInt((max - min) + 1) + min;
}
