[EnumMap]——基本用法

public class EmuMap {
public static void main(String[] args) {
EnumMap<Season, String> map=new EnumMap<Season,String>(Season.class);
//存放值
map.put(Season.SPRING, "春困");
map.put(Season.SUMMER, "下午里");
map.put(Season.AUTUMN, "求噶");
map.put(Season.WINTER, "冬眠");
System.out.println(map.size());
}
}
enum Season{//季节
SPRING,SUMMER,AUTUMN,WINTER;
}
