You may collaborate on this homework with AT MOST one person, an optional "homework buddy".

MAY ONLY BE TURNED IN IN THE LECTURE/LAB LISTED ABOVE AS THE DUE DATE,
OR IF APPLICABLE, SUBMITTED ON GRADESCOPE. There is NO MAKEUP for missed assignments;
in place of that, we drop the four lowest scores (if you have zeros, those are the four lowest scores.)

(10 pts) Please fill in the information at the top of this homework sheet, including your name and umail address. Put the time your discussion section starts (4pm, 5pm or 6pm) in the space indicated (the one you are registered for—even if you usually attend a different one.) If the other two items apply, please fill them in as well. Please do this every single time you submit homework for this class.
This worksheet is practice at understanding interface vs. inheritance. For this worksheet, you need the additional [handout A](handout_a/) with code for these files: `Beverage.java`, `Edible.java`, `Food.java`, `FreeCandy.java` and `Product.java`. These are classes used by a grocery store known as "Trader Bobs". Some of these methods will compile and run, while others will not. Indicate, for each method, where it compiles or not, and if it does compile, the output when invoked. in context of the classes on [handout A](handout_a/) and assuming the methods appear inside this class: ```java public class TraderBobs { // methods appear here } ```

Will it compile? Output when called (only if it compiles)

☐ Yes
☐ No
