CS112: In-class Exercise 9 (improved) Grab the BlueJ project myclock from public \ Yuen(CS) \cs112BlueJ in the lab. When reading the following, pay attention to which class is being discussed. 1. Modify the ClockDisplay class by adding a new method called displayAMPM() which will display the time in 12 hour format. This will necessitate adding new methods to NumberDisplay class. Add a new method displayHour12() to the NumberDisplay class that will display its internal number n as if it is an hour number in 12 hour format. This means a 0 will be displayed as a 12, any number from 1 to 12 is displayed as itself, and any other number will have 12 subtracted from it. Use a temporary local variable, say x . Make an if-elseif- else statement that computes x based on n . Then print x to the Terminal Window analogous to the printing that was done in the regular display() method. Add a new method displayAMorPM() to the NumberDisplay class that will display the letters “AM” or “PM” treating the internal number as an hour in 12 hour format.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
