Question

Which of the following headers for a generic method myMethod allows the actionPerformed method from the ActionListener class to be called?

I public static E myMethod(E e)
II public static E myMethod(E e)
III public E myMethod(E e)

Answer 1

The provided method signatures do not allow for the actionPerformed method of the ActionListener interface to be called as they are generic methods, whereas actionPerformed requires a specific ActionEvent parameter and is not generic.

Step-by-step explanation:

The question is asking which method signature would allow a generic method myMethod to call the actionPerformed method from the ActionListener interface in Java. The signatures provided are:

• public static <E> myMethod(E e)
• public static <E> myMethod(E e)
• public <E> myMethod(E e)

None of these method signatures directly allow for the actionPerformed method to be called because the signature for actionPerformed specifically requires an ActionEvent parameter and does not relate to the generic type parameter E. The signature of action performed is:

public void actionPerformed(ActionEvent e)

To call actionPerformed, the method signature must be that of a class that implements ActionListener, either anonymously or as a named class, and should not be a generic method.
