You have to make use of inheritance and polymorphism here. Declare a
"base" class (possibly abstract) and give it a setController method.

 public abstract class MyBase {
   public abstract void setController();
   }
  
Alternatively, declare an interface that has a setController method.

 public interface MyInterface {
   public void setController();
   }

Now, each of your classes that has a setController method should
either extend MyBase or implement MyInterface:

 public class MyClass extends MyBase {
 
   public void setController() {
     // stuff goes here
     }

   }

or

 public class MyClass implements MyInterface {

   public void setController() {
     // stuff goes here
     }

   }

Finally, your addToDict method should be declared like this:

 public void addToDict(String key, MyBase value) ...

or

 public void addToDict(String key, MyInterface value) ...

The bottom line is that you have to let the compiler know that value
represents an object instance that does indeed have a setController
method.
