600.108 Intro Programming Lab                                 Week 13


***********************************************************************
       PLEASE COMPLETE COURSE SURVEYS and RETURN TO YOUR
   	             LAB LEADER BEFORE YOU BEGIN!

***********************************************************************


For this final week you'll be putting some actual error-checking
(exception handling) into your programs!  To start with, get with your
partner from last week and download your (or our) solution to last
week's lab.


Phase I: Create a custom exception class and use it to report invalid
times in the Time class.  Also use it to handle invalid times in the
other classes that try to create Time objects.  This should be similar
to the InvalidCardException.java file that we saw in lecture this
week.  Test and show to your lab leader.


Phase II: Create a new driver program (week13.java) that starts as a
copy of week12.java.  Handle JDK IO exceptions in main, particularly
those that might be thrown from read methods of your other classes.
See the exceptions*.java files from lecture for examples of this.
Test and show to your lab leader.


Phase III: Handle attempts to put more than 20 members in a planner
object.  How you do this is entirely up to you.  Test and show to your
lab leader.


Phase IV: Congratulations!  You have completed the Java Lab Course!

   MAKE SURE YOU DELETE YOUR FILES OFF THE LAB COMPUTER WHEN DONE!!!
             FAILURE TO DO SO IS AN ETHICS VIOLATION!
