CSC152 2005F, Class 25: Review of Control Structures

Admin:
* Questions on the homework?

Overview:
* A motivating problem: Parsing to integers
* Conditionals
* Loops
* Exceptions

String equality testing
	str.equals(otherString)

Hard part: How do you convert a string that is a sequence of digits
to an integer?
Suggestion one: Start at the right, extract each digit, and multiply by the place value

E.g., "4218"
  There's an 8 in the rightmost place, 8*1 = 8
  There's a 1 in the next place, 1*10 = 10
  ...
  4000 + 200 + 10 + 8 = 4218
Concern about potential overflow

Alternative:
* Take the first digit
* Recurse on the rest
* Combine somehow
