java.lang.ClassCastException: java.lang.String cannot be cast to [Ljava.lang.Object

Question

I\'m running the following query. It displays an error message. How to solve this error?

        ListrouteList=null;
        List compa         


        

Answer 1

You can just write:

vgDetails = new Route();                                 
vgDetails.setRouteName ((String)companyList.get(i));

companyList is already a list of strings because you select just one column.

Additionally, as Thilo's answer also suggests, you can cast your result directly to a List instead of using List.
