The Learning Journal is a tool for self-reflection on the learning process. In addition to completing directed tasks, you should use the Learning Journal to document your activities and record problems you may have encountered in discussions and projects. Each week’s Learning Journal entry should be a minimum of 250 words.
Use the following questions as guides to self-reflection during this week:
Briefly describe what programming you did this week.
Describe any problems you have had and how you solved your problems.
Describe any feedback you received in class and discuss how it was or was not helpful.
What skills and knowledge do you recognize that you are gaining, and how will these skills and knowledge be useful in school and as a professional after school?
Describe:
The code below uses the SWING library to further demonstrate how to create base classes such as a Person or a CollegeEmployee that can be extended to a student or a Faculty member, a Faculty member who is an extension of a Person, and a CollegeEmployee to the Faculty member class.
