To help manage the wizarding world, we need to write a merge method. For the general purpose, let us write a generic merge method. Namely, given two arrays of T objects, for example, Hogwarts students, the merge method would use stacks to merge these two T objects in the way specified in the above mentioned description and return a new ArrayList with these T objects in a special order.

The generic method prototype is as follows:

public ArrayList merge(T[] wizards1, T[] wizards2) throws Exception;

To help reverse Hogwarts students' names, we can invoke the method as follows:

merge({2, 4, 1}, {5, 7, 3})

where {2, 4, 1}, {5, 7, 3} is two array inputs and it will return an java. util. ArrayList instance, containing {1, 3, 4, 2, 7, 5}

Please use Stacks to implement the generic reverse method:

public ArrayList merge(T[] wizards1, T[] wizards2) throws Exception;

Task 2. (12 points)

Please write a test block of code by calling the method and handling the possible exception, where a String array is declared and initialized, invoke the merge method that you define and implement in the task 1. Since the merge method could throw an exception instance, we also need to write a try-catch block in order to handle the exception.
