Java Programming: Stack ADT(abstract data type) implemented with an array

Using the interface create a simple stack class -> Use an array as the underlying data structure. -> Try to pass all the included unit tests (hint : import java.util.EmptyStackException)

-> Add the missing test (Test Coverage) (if you dont need another test, you forgot something )

Add methods should look like ( in the Stack class): add unimplemented methods

* Hint you need a constructor that creates the array something like this: * stackItems = (Item[]) new Object[maxSize];

public class Stack implements StackInterface { @Override public void push(Item item) { // TODO Auto-generated method stub @Override public void pop() { // TODO Auto-generated method stub @Override public Item top() { // TODO Auto-generated method stub return null; @Override public Item topAndPop() { // TODO Auto-generated method stub return null; Stackinterface - Notepad File Edit Format View Help //No need to update this file public interface StackInterface { * Insert a new item into the stack. * @param item the item to insert. public void push(Item item); * Remove the most recently inserted item from the stack. public void pop(); * Get the most recently inserted item in the stack. Does not alter the stack. public Item top(); * Return and remove the most recently inserted item from the stack. * @return the most recently inserted item in the stack. Item topAndPop(); * Test if the stack is logically empty. * @return true if empty, false otherwise. public boolean isEmpty(); *Make the stack logically empty. public void makeEmpty(); *Return the size of the stack. public int size()
