Specifying a generic type in java from Class object

Question

Why this is wrong:

    Class<? extends Number> type = Integer.class;
    ArrayList<type> = new ArrayList<>();

?

Is there no way to instantiate a class of a specific type given a class object?

---

Obviously I would never do that directly, that is just an example to show what is needed. In the actual code I need I don't know the name of the type. For example

    public void createAList(Class<? extends Number> type)  
{
    ArrayList<type> toReturn = new ArrayList<>();
    return toReturn;
}

Answer 1

<T extends Number> ArrayList<T> createAList(Class<T> type)  
{
    ArrayList<T> toReturn = new ArrayList<>();
    return toReturn;
}


ArrayList<Integer> intList = createAList(Integer.class);
