lect03c
if-else (cont.)
and hw01, javadoc, ...

side notes on board:

When writing test cases:
 - When testing ints, include 0,1 if whenever sensible
   (and a negative number and a larger number)

 - When testing Strings, include a string of length 0 and a string of length 1
   whenever sensible (and a larger string)

 - When testing booleans, include both false and true.


Phrase:
 - the *purpose* of a local variable is to compute a partial result
    of the overall answer,
   giving a name to it so you can use it again in the following lines.

 - (Btw: ditto for "helper" functions.  E.g. helper bowtie
   for overall task smileyFace,
   which in turn is sometimes a helper for threeSmileys).

• Pass back hw01; discuss some common problems and the general-grading-guide—general grading guide
• if-else statements:
  • apply to Pizzeria.buffetPrice
  • apply to Pizzeria.crustArea
  • syntax
  See the code before and after.
• Javadoc (for buffetPrice)
• Functions taking in a boolean;
  Functions returning a boolean
  (as per lect03b—booleans and if-else)
• Nesting ifs:
