Mutable objects can be corrupted by multiple threads accessing them concurrently.

Consider a partial version of Bloch’s mutable Stack class: public class Stack { private Object; } public void push (Object e) { ensureCapacity(); // implementation omitted from quiz elements = e; } public Object pop () { if (size == 0) throw new IllegalStateException(“Stack.pop”); Object result = elements; elements = null; return result; } } Also consider the following client interaction with Stack Stack s = new Stack(); s.push(“apple”); s.push(“orange”); System.out.println(s.pop()); What methods would be needed to convert the client interataction into an equivalent interaction with an immutable version called IStack? For each method, give just the method header – not the contract or implemetation. Choose the most correct answer.

Mutable objects reduce the freedom of the client and implementer to change independently.

What is the purpose of the ensureCapacity method in the Stack class below? public class Stack { private Object; } public void push (Object e) { ensureCapacity(); elements = e; } public Object pop () { if (size == 0) throw new IllegalStateException(“Stack.pop”); Object result = elements; elements = null; // Eliminate obsolete reference return result; } private void ensureCapacity() { if (elements.length == size) { Object oldElements; System.arraycopy(oldElements, 0, elements, 0, size); } } }
