We go back to basics this week.

Q: Given the following interface definition:

interface Foo {
  int ZERO = 0;
  public int ONE = 1;
  public static int TWO = 2;
  public static final int THREE = 3;

  void first();
  abstract void second();
  public abstract void third();
}

Which of the following are true (choose all that apply):

1. ZERO is not public
2. ONE is not static
3. TWO is not final
4. first() is not abstract
5. second() is not public
6. None of the above
7. One of the above
8. Two of the above
9. Three of the above
10. All of the above

And we revert back to strict rules: no books, no googling, no internet, no compiling. Just stare at the code and think.
