• Copies of your submissions for projects 4, 5, 6a, 6b, 7, and 8.
• Some Java Classes and Methods document.
• No calculator (not needed)

Possible Final Exam Format

• Multiple choice questions. Give an optional reason or show your work for each question.
• Short essay questions. Choose one question to answer out of three. For full credit, write in complete sentences with an introduction and conclusion.
• Find the errors in Java class files.
• Predict output of Java class files.
