I want to implement generic java method passing argument as class object and defining method parameter as Class or T type

Question

I want to achieve generic java method that it should be pass class object in method parameter

E.g :

My method definition Here in different project class

public String getRtbAd(HttpServletRequest request, T userProfileClass,
            List<String> systemControlDetails, T wurflDataGenericClass,String redisConnectionUrl, String dimension, Short rtbTimeOut) 
{

//My Bussiness logic

}

Here,actully I am calling method from different project class

public String getRtbAd(request, userProfileObject,
            systemControlDetails, wurflDataGenericObject,redisConnectionUrl, dimension, rtbTimeOut)

And what is the problem? How does look your class definition? — tak3shi, Jun 17 '16 at 10:35
if only your method is using generic include before return type in your method signature. Can u specify what is the problem? — Akash Lodha, Jun 17 '16 at 10:56
Issue is i am not getting the instance of userProfileObject and wurflDataGenericObject on runtime — anandchaugule, Jun 23 '16 at 10:33

First of all if T userProfileClass and T wurflDataGenericClass are different types then they should be having different literals as their type. They must be mentioned like T1 userProfileClass and T2 wurflDataGenericClass.
The class in which this method is mention should accept these types like below:-

    public class myClass {        
        public String getRtbAd(HttpServletRequest request, T1 userProfileClass, List systemControlDetails, T2 wurflDataGenericClass,String redisConnectionUrl, String dimension, Short rtbTimeOut){     
            }        
        }        
        myClass  a = new myClass();
        String str = a.getRtbAd();

=========== I am really not sure why this comment window is not displaying my generic code correctly.Following are not shown.

myClass < T1, T2 >
myClass < ProfileClassName, DataGenericClassName > a = new myClass< ProfileClassName, DataGenericClassName >();

Yes exactly i will try this approach . Thank you – anandchaugule Jun 23 '16 at 10:37 — anandchaugule, Jun 23 '16 at 10:37
