How do I do the equivalent of "myClass[].class" with ArrayList<myClass>?

I wish did fix the issue. In Gson, you use a TypeToken to represent a generic type. Note the {} in there; it's necessary because it creates a subclass of TypeToken with the generic type information.
List<MyClass> list = new Gson().fromJson(responseString, 
    new TypeToken<ArrayList<MyClass>>(){}.getType());

ArrayList<MyClass> vs MyClass[26]?

will be helpful for those in need You're asking the wrong question. Whether an ArrayList might take a bit more space than a plain old array is quite besides the point.
The question that you really need to answer in order to decide which one to use is whether you will ever need to dynamically resize the array.

wish helps you Override the filterOn() method to create the instance you wish in MySubClass :
 public class MySubClass extends MyClass{

    public MyClass filterOn(String something){
       MySubClass result = new MySubClass();
       result.doSomethingUsingThisInstance(this, something);
       return result;
    }
   ....
 }
public class MyClass {

   public MyClass(){
     }

   public MyClass createSpecificInstance() {
     return new MyClass();
   }

   public MyClass filterOn(String something){
       MyClass result = createSpecificInstance();
       result.doSomethingUsingThisInstance(this, something);

      return result;
   }

}
public class MySubClass  extends MyClass {

   public MyClass createSpecificInstance() {
     return new MySubClass();
   }

}

How do I add an instance of type MyClass to an array of MyClass, declared in MyClass, inside the constructor of MyClass?

Hope this helps In order to keep track of instances, we have an array MyClass[] mc = new MyClass[5]; , You can do this in your constructor:
classList[number++]  = this;

function MyClass(){ ... }; MyClass.prototype = MyClass; -- considered harmful?
