Rhythmk 一步一步学 JAVA (18): Enum枚举学习

public enum SizeEnum {
     SMALL,
     BIG,
     BIGEST
};

public enum SizeStringEnum {

    SMALL("小"),
    BIG("大"),
    BIGEST("巨大");

    private String strSizeString;

    public String toString() {
        return strSizeString;
    }
     private SizeStringEnum(String str) {
        this.strSizeString = str;

    }

}

//1、
        SizeStringEnum sizeStringEnum=SizeStringEnum.BIG;
        for(SizeStringEnum size: sizeStringEnum.values())
        {
             System.out.println(size);
        }

//2、
           for(SizeStringEnum size:     SizeStringEnum.values())
        {
             System.out.println(size);
        }

        sizeStringEnum=Enum.valueOf(SizeStringEnum.class, "BIG");
