枚举enum

public class EnumTest {

public static void main(String[] args)
{

judgeColor(colorful.BLUE);
}

public static void judgeColor(colorful color)//写成静态方法，是因为上面的main函数即时调用
{
switch (color)
{
case RED:
System.out.println("RED");
break;
case BLUE:
System.out.println("BLUE");
break;
case YELLOW:
System.out.println("YELLOW");
break;
case GREEN:
System.out.println("GREEN");
break;
