Enum types - Nice Trick!

Effective Java Reloaded (Google I/O Session Videos and Slides)

public enum Ensemble {
SOLO(1), DUET(2), TRIO(3), QUARTET(4), QUINTET(5),
SEXTET(6), SEPTET(7), OCTET(8), DOUBLE_QUARTET(8),
NONET(9), DECTET(10), TRIPLE_QUARTET(12);
private final int numberOfMusicians;
Ensemble(int size) {
numberOfMusicians = size;
}
public int numberOfMusicians() {
return numberOfMusicians;
}
}
