+1. Question 1
+Suppose a web log is modified to now have a sixth piece of information, a priority, that can be represented as a String.
+
+Which one of the following is the least likely change to the LogEntry class to accommodate this new part of a web log?
+
+A new String parameter is added to the constructor.
+
+A new private variable named priority is created.
+
+A new String field is initialized in the constructor.
+
+A new getPriority method is created to return the priority.
+
+The toString method is modified to include a String parameter.

+The toString method is modified to include the new priority as part of the return String.

+2. Question 2
+
+Consider the following code for the readFile method of the LogAnalyzer class.
+

+In the Tester class, readFile is called with a correct filename, and then printAll is called, but nothing is printed.

+Which one of the following is likely the best reason why?

+In readFile, the log entries were not stored in records.

+3. Question 3
+Consider the following code for the method printAllHigherThanNum with one integer parameter num. This method should print all the logs that have a status code higher than num.
