Answer 1

The exception NullPointerException under @Test method of Login class because Setup.initialize(); initialize the driver in Setup class only You wont get the same reference under Login class and the driver instance under Login class remain null.

Either You need to return the driver instance from Setup class and use that in Login class or extend the Setup class in Login class
