How to instantiate a class in custom controller from within controller extension?

Question

This should be simple. I have a custom controller like so

    public class MyClass {
    .
    .
    .
    public class MyType{
      String a;
      Integer b;
      List<Account> c;
    }
    .
    .
    .
    }

Now I am trying to instantiate MyType object from a controller extension, like so:

public class MyClassExtension {

    public MyClassExtension(MyClass controller) {
        // This is where I need help
        controller.MyType myTypeObj = new controller.MyType();
    }

How do I do this? A couple of syntaxes I tried resulted in errors. TIA.

To instantiate a subclass you would need to prefix the parent class name, not its variable reference. Try this.

MyClass.MyType myTypeObj = new MyClass.MyType();
