```plaintext Question 1: public interface StackInterface<T> { void push(T element) throws StackOverflowException; void pop() throws StackUnderflowException; T top() throws StackUnderflowException; boolean isFull(); boolean isEmpty(); } Show what is written by the following segments of code (see println on the code), given that item1, item2, and item3 are int variables, and ali is an object that fits the abstract description of a stack as shown above StackInterface. Assume that you can store and retrieve variables of type int on ali. item1 = 2; item2 = 0; item3 = 6; ali.push(item2); ali.push(item1); ali.push(item1+item3); item2 = ali.top(); ali.pop(); ali.push(item3+item3); ali.push(item2); ali.push(3); item1 = ali.top(); ali.pop(); System.out.println(item1 + " " + item2 + " " + item3); while(!ali.isEmpty()) { item1 = ali.top(); ali.pop(); System.out.println(item1); } ``` ### Explanation This code defines a stack interface and manipulates an object `ali` that implements this interface. It demonstrates various stack operations: - `push`: Adds elements to the stack. - `pop`: Removes the top element from the stack. - `top`: Retrieves the top element without removing it. - `isEmpty`: Checks if the stack is empty. The given code segment performs a series of push and pop operations and uses the `top` method to manipulate integer variables. The code finally prints out the values of `item1`, `item2`, and `item3`, followed by the contents of the stack until it is empty.
