Description
You will complete a program to process your study log and learn more about yourself as a student.
Download the template file StudyStats.java from Assignment #4 on conneX. Write the missing
code for the methods in this template and as usual, compile and test your code often as you write
it up.
Make sure to back up your study log.txt file while working on it, in case you accidentally erase
the contents of the file. You can test your code on an a sample study log, study log check.txt
also available for download from Assignment #4 on conneX.
A sample run for the completed program on the check file outputs the following:

I recommend starting with simply understanding the code in the template as it is written before
you begin to work, and become more familiar with the start and stop arrays. Walk through the
code and convince yourself that it is storing the file entry data into the arrays. You can see the
output printed as the arrays are filled with the helper method printEntry.
Then start with the timeInMins method, and make sure it calculates the number of minutes from
midnight to the input parameter time correctly.
Then use timeInMins to help you write the next method entryMins (you can actually write this
method in one statement). This method should return the total number of minutes in an entry,
from its start to its stop time. You should not have any entries in your log with start time before
midnight, and stop time after midnight on the morning of the next day. If you do, simply split the
entry into two entries, one for each day.
Then use entryMins to help you write aveStudyMins (make sure to cast the total number of
minutes as type double in your final calculation, before you divide). This method should calculate
the average number of minutes across entries in your log. You can then see for yourself how much
time are you spending on average when you decide to study.
You can also use entryMins to help you write maxStudyTimeEntry (see min/max loops on pg. 256
in your textbook). Note that you can also save the index of the maximum entry you find with
an integer variable, not just the maximum value itself. You can then see what activity made you
spend the most time in one study session.
There are many more things you could program yourself to find out about your study habits.
If you decide to write a method to test parts of your code, you could leave that extra code in your
submission, but make sure to get rid of any calls to it before you submit. If you have an adequate
testing method, then it can earn you up to 5 buffer marks (doesn’t contribute to a mark above 30).

Grading
Marks will be allocated out of 30 points:
• (0 points) You do not submit any program file.
• (5 points) Your program does not compile. The marker cannot fix the complier error easily,
or if they can, the output is severely mismatched with the assignment requirements.
• (10 points) Your program does not compile, but the marker can fix the error easily.
• (15 points) Your program compiles, but only outputs a few of the assignment requirements.
• (20 points) Your program compiles, outputs most of the assignment requirements, and is
missing documentation comments or has formatting issues.
• (25 points) Your program compiles, outputs everything required, but is missing documentation comments or has formatting issues.
• (30 points) Your program compiles, outputs everything required, and has proper documentation and formatting.
