圣杯 2.2
所以这应该很容易，但是我不断收到相同的错误消息：
Class java.lang.IllegalArgumentException
Message No enum constant myPackageName.RequestType.Banner
这是我的课：
public enum RequestType {
BANNER("Banner"), OTHER("Other")
final String value
RequestType(String value) { this.value = value }
String toString() { value }
}
这把我逼疯了！！
编辑：堆栈跟踪
No enum constant myPackageName.RequestType.Banner. Stacktrace follows:

这是它在课堂上的使用方式
class Project {

RequestType requestType
...
}
