    Did You use List in your application?
    Using List we can store Object ,Then why do you need casting?

    hi,

    routeObjList.get(0).locationId

    if I use statements like this it is not accepting where locatioIid is attribute of class route.

    Default Sample

    ArrayList<emp> Obj=new ArrayList<emp>;
    Obj.add(new emp());


    Simple syntax for store object in arraylist,It works quite well.

    As for me,casting is not a good practice for good programmers.Casting is a shortest way to solve big problem.So,Don't use casting in Application.
    Thanking You.
