Test code for part 5:


HashSet<String> hashSet = new HashSet<>();
hashSet.add("String 1");
hashSet.add("String 2");
AmigoSet amigoSet1 = new AmigoSet(hashSet);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(baos);
oos.writeObject(amigoSet1);
oos.close();
ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray());
ObjectInputStream ois = new ObjectInputStream(bais);
AmigoSet amigoSet2 = (AmigoSet) ois.readObject();
System.out.println("Before serialization:\n" + amigoSet1 + "\n");
System.out.println("After deserialization:\n" + amigoSet2 + "\n");
System.out.println("Are sets equal? - " + amigoSet1.equals(amigoSet2));

Hint for task 5: Look at what data type loadFactor is (it's not the same type as Capacity).

Woohoo - task 5 was a little bit of a refresher in terms of serialization. Pretty cool to use this in conjunction with the provided HashMapReflectionHelper. Thank you, Captain Squirrels, Sir! :-)
