Question
The program contains a main for the program. This can be left unedited. You can add more code if you like, but do NOT delete or change any code already written.
SectionProblemLog.java has a number of places that indicate YOUR CODE GOES HERE. It will be your job to insert code at those points to make the methods works as indicated. See the sample jar file for details on formatting toString (it is 'X' for true and '_' for false).
