Day 16: Error Handling and Security

Notes and Corrections

  • Page 441: The exercises in this chapter are duplicated from Day 15. Try these exercises as an alternative:
    • Create a modified version of the HexRead application that pauses for 10 seconds whenever a decimal value of 25 is read.
    • Create an application that takes a command-line argument and determines if it is an integer or not, using the Integer.parseInt() method described on Day 6. This method throws a NumberFormatException.
