本文介绍了一个简单的Java枚举类型的实现案例，通过定义成功与失败两种状态，并提供了通过代码获取描述的方法。

public class EnumPrac {
    public enum Demo{
        SUCCESS(1,"成功"), FAIL(0,"失败");
        private Integer code;
        private String desc;
        private Demo(Integer code ,String desc){
            this.code = code;
            this.desc = desc;
        }
        public Integer getCode() {
            return code;
        }

        public String getDesc() {
            return desc;
        }

        public void setCode(Integer code) {
            this.code = code;
        }

        public void setDesc(String desc) {
            this.desc = desc;
        }
        private static Demo getTypeByCode(Integer code){
            Demo defaultType = Demo.FAIL;
            for(Demo demo : EnumPrac.Demo.values()){
                if(demo.code == code){
                    return demo;
                }
            }
            return defaultType;
        }

        public static String getDescByCode(Integer code){
            return getTypeByCode(code).desc;
        }
    }

    public static void main(String[] args) {
        System.out.println(Demo.getDescByCode(1));
        System.out.println(Demo.getDescByCode(2));
        System.out.println(Demo.getDescByCode(3));
    }
}
