JDK5.0 新機能：enum

「4.1. 簡単な enum」

ほぼ、まんま

enum C2008081900_Color { RED, BLUE, YELLOW, BLACK, WHITE }

public class C2008081900 {
    public static void main(String[] args) {
        C2008081900_Color white = C2008081900_Color.valueOf("WHITE");

        System.out.println(white);
    }
}

で、

WHITE

javap -c を実行
