Question

I have an abstract method

public abstract Class<? extends MyClass> getMySpecialClass();

In another method I’d like to have an instant of this class. How would I do this?

public void method(){
   Class<? extends MyClass> mySpecialClass = getMySpecialClass();
   MyClass myClass = new ???
}

Answer 1

How about calling newInstance?

MyClass myClass = mySpecialClass.newInstance();

The class must have a nullary constructer (one with no parameters).
