The weather __________ (be) very different when the semester ends next month.

My parents __________ me a lot about life when I was a child.

One of the students __________ to class early every day.

Everyone __________ the homework.

Mutable types are generally better for (select all correct answer(s) and no incorrect answer(s) to get credit):

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

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

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.

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); } } }
