}*///如何定义枚举的构造函数，方法和字段，去封装更多的函数enum Grade1{ //classA("100-90"){public String localValue(){return "优秀";}},B("89-80"){public String localValue(){return "良好";}},C("79-70"){public String localValue(){return "一般";}},D("69-60"){public String localValue(){return "合格";}},E("59-0"){public String localValue(){return "不及格";}};private String value;private Grade1(String value){this.value = value;}public String getValue(){return this.value;}public abstract String localValue();}
