Casting - foreach - java

Question

I have a one method like this:

private void myMethod(List<?> myLists) {

   for (Object val : myLists) {
       val.getMyOtherMethod(); // for example
   }

}

How can I casting val to one of my objects?

All my objects (list objects) contain same methods, like as getMyOtherMethod()

BR

edit: ---------------------------------------------------------------------

I called myMethod few times, like as:

List<MyClas.MySubclass1> var1;
List<MyClas.MySubclass2> var1;
List<MyClas.MySubclass3> var1;
...
...

myMethod(var1);
myMethod(var2);
myMethod(var3);

In this case, I do not know, witch subclass I send MySubclass1, MySubclass2 or MySubclass3. That is important for foreach loop.

Answer 1

You need a List of elements which implement getMyOtherMethod()

interface ImplementsGetMyOtherMethod {
   void getMyOtherMethod();
}

private void myMethod(List<? extends ImplementsGetMyOtherMethod> myLists) {
