Agenda

  1. Warm-up: Spot the Bug — a program that crashes on the last line of the file
  2. The blank line, the missing file, the letter where a number belongs: what a program should DO about each
  3. Read and change: the exception handling in Reading and Writing Files
  4. Add one guard to your own program, and prove it works by breaking the file on purpose
