Someone gave me a call one day. I didn't apply, so I guess it was a recruiter.

I answered all their questions, and they never called me back. They never sent me an email, and when I called to ask, they told me, "Tough luck."

1. Verbal Test:

a) What's the difference between StringBuffer and StringBuilder?

b) What's the difference between a LinkedList and an ArrayList? When would you use each?

1. Language Quiz - Strings

a = "hello"; b = "hello"; c = new String("hello"); d = c; e = new String("hello");

Tell me the result:

a) a == b

b) a.equals(b)

c) a == c

d) c == d

e) c.equals(d)

f) c == e

g) c.equals(e)

1. Code Time!!!

Program a method that returns an inOrder ArrayList of the nodes in a tree:

public ArrayList inOrder(Node root);
