Switch Enum使用

以为在Switch中使用Enum应该这样用，可是却编译不通过

package cn.cjf.java.enums;

import lombok.AllArgsConstructor;
import lombok.Getter;

public class SwitchEnumTest {
   public static void main(String[] args) {
       int code = 1;
       final EColor color = EColor.getByCode(code);
       switch (color) {
           case EColor.RED:
               System.out.println("红色");
               break;
           case EColor.GREED:
               System.out.println("绿色");
               break;
           case EColor.BLUE:
               System.out.println("蓝色");
               break;
           default:
       }
   }

    @Getter
    @AllArgsConstructor
    public enum EColor {
        RED(1), GREED(2), BLUE(3);
        private int code;

        public static EColor getByCode(int code) {
            for (EColor color : EColor.values()) {
                if (color.code == code) {
                    return color;
                }
            }
            return null;
        }
    }
}

但去掉类名后，却可以

package cn.cjf.java.enums;

import lombok.AllArgsConstructor;
import lombok.Getter;

public class SwitchEnumTest {
    public static void main(String[] args) {
        int code = 1;
        final EColor color = EColor.getByCode(code);
        switch (color) {
            case RED:
                System.out.println("红色");
                break;
            case GREED:
                System.out.println("绿色");
                break;
            case BLUE:
                System.out.println("蓝色");
                break;
            default:
        }
    }

    @Getter
    @AllArgsConstructor
    public enum EColor {
        RED(1), GREED(2), BLUE(3);
        private int code;

        public static EColor getByCode(int code) {
            for (EColor color : EColor.values()) {
                if (color.code == code) {
                    return color;
                }
            }
            return null;
        }
    }
}
