Changes 10/28/14

Java:

• Did the first Stringlist activity, where you are essentially creating a string-like class that follows the ADT list interface.  
• I was unhappy because it forced me to use string concatenation where a StringBuilder would have been much more efficient.  
• The underlying store of character data in the eimacs implementation was a String. Replacing this String with a StringBuilder make much more sense, as the object's implementation of List interface methods like #add() and #set() suggests that the underlying data will be modified quite a bit.
• I also had some trouble during that activity because I couldn't figure out how to get the length of a string.
• This caused me to realize that Java's naming conventions are really counter intuitive, and place too much emphasis on implementation details. 
• To get the length of an array, you call Array[].length;
• To get the length of a String, you call String#length();
• To get the length of a List, you call List#size();
• The reason I took 10 minutes trying to figure out how to get the length of a string was because I falsely remembered that you didn't need brackets after it.  A programmer really shouldn't need to care that the length of an array is a static field while the length of a String is a method, but Java forces you to know that because you must put brackets after #length when calling it on String.
• Then, they take this and just throw it all out when implementing ADT list, making it #size() instead.  I was also falsely under the impression that the naming convention was .length when the length is a static field and #size() when the length must be found using a method, but this is not the case.
• If I was using Eclipse or IntelliJ, I would have figured this out right away, but the eimacs web interface doesn't have tab completion. 

Life Skills:

• Learned how to order pizza online, which I had never done before.  People were kinda mean about it though, and acted like I was stupid for not knowing exactly how to do my first time.
• Learned that the Dominos website shows you coupons, which I guess is to make you feel like you are spending less on pizza.  One coupon cut our order from $30 to $20, and that $20 seems like much less when compared to the $30 than it might if that was the original order price.
• I'm assuming that's what their going for, because it's kinda stupid that you can get the exact same order for a drastically different price depending on whether you click on the site a couple of extra times or not
