Recently stumped upon this line in a program, and I have no idea what the bracket for (List<Level>) is for . Anybody got any idea ?
List<Level> levelList = (List<Level>)dao.getAllLevels();
Its called typecasting. The data returned from dao.getAllLevels() is being casted into type
List.This operation might not always be successful, and in that case
jvm/jrethrows aClassCastException. You can read more about object typecasting in Java here.More about java and type-casting on Stackoverflow:
