Please help with designing and implementing the test class. Also show some sample output screenshots if possible.

The implement a stack data structure using a generic array. I can help you with that! First, let me start by providing the interface you'll need to implement the stack ADT: public interface StackInterface T \{ public void push(T item); public T pop(); public T peek(); public boolean isEmpty(); public int length(); public String toString0; 3 let's discuss designing and implementing the test class according to the given specifications. At minimum, the implementation must implement the provided interface and also override the to String method. You should create an instance of the specified stack. you can design and implement your test class: 1) Create a test class with a main method 2)Instantiate your stack instance with the generic type 3) Test all the operations like push(), pop(), peek(), isEmpty(), and length() 4) Use assertions to check all edge cases, like what happens when you pop from an empty stack or push to a full stack 5)Override the toString() method in the test class and test different scenarios 6)Lastly, create a menu-driven application that tests the push(), pop(), and peek() methods using integers
