我有一个案例类

case class AGG_RECON(SUBSCRIBER_ID:String , ChargingID:String ,NodeID:String, START_TIME:String, DXE_First_Report_Time:String, DXE_Last_Report_Time:String, DXE_Session_Start_Time:String, DXE_Bearer_Creation_Time:String, DXE_IMSI:String, DXE_MSISDN:String, DXE_RAT_Type:String,

result


}

当我执行我的应用程序时，这个类在编译时没有给我任何错误，它给了我

＆＃34;除了类或对象定义＆＃34;在toString方法之前的第一个括号上..我正在使用scala 2.11.5 ..我真的不知道是什么问题？

Answer 1

不，它是编译错误，而不是运行时异常。
类主体之前的空行告诉编译器
```
case class AGG_RECON(...)
```
是完整的定义，
```
{ 
  override def toString = ...
}
```
是一个不相关的块，但您不能在Scala文件的顶层有块。删除)和{之间的行，一切都会有效。

scala中的case类给了我运行时异常
