case classes in scala gives me runtime exception

I have a case class

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


}
}

This class doesnt give me any error on compile time when I excute my application, it gives me

"excepted class or object definition" on the first bracket before toString method..I am using scala 2.11.5..I really dont know what is the problem?

  1. No, it's a compilation error, not a runtime exception.

  2. The empty lines before the class body tell the compiler 

    case class AGG_RECON(...)

    is the complete definition, and 

    { 
  override def toString = ...
}

    is an unrelated block, but you can't have blocks on the top level of a Scala file. Remove the lines between ) and { and everything will work.
