Test Prep 7 - Mock Test #1

A. Review 1) HW check 2) Kahoot! B. H. What are Javadoc Comments? What do @param and @return do? (@throws is useful but won't be tested.) What does short circuit evaluation of logical operators do? I. Which operation has the lowest precedence? J. What is the difference between nested ifs and sequential ifs? What about nested loops and sequential loops? K. How to call static methods and pass arguments?

A. Two parts: 50% weight is MC and 50% is FRQ MC: 90 minutes, 40 questions, 1 point each question. No penalty for wrong answers (Yes, take your guess!) FRQ: 90 minutes, 4 coding problems, 9 points each problem. Write code on paper, no penalty for minor syntax errors. B. Strategy for MC: Roughly 2 minutes per question - stay focused when practice Guess is okay - mark guesses for review when time allows An active pencil - hand trace loops, write return values on booklet, use small matrix as examples to test an algorithm Summarize more strategies for each subject when practice C. Strategy for FRQ: 20 min for each question READ carefully, highlight important conditions, restrictions, requirements Write whatever you can, even though it's incomplete The four problems are almost always of the following: Class and objects - how to define classes, create and use of constructors 2-D array - of primitive values, Strings or objects ArrayList of Strings or objects, may use inheritance Interface

A. Introduction Anything is possible if you can program... :) B. Watch (Slides) C. Try: 1) Do you know ArrayList class is implemented by an array? 2) Can you implement insert/remove for 2-D arrays?
