Contact Jonathan Sanders if you need to make other arrangements (jsanders@cs.washington.edu).

Exam Rules and Information:

• You may sit anywhere in the room, but we want to have alternate seating (so at least one empty seat between every pair of students).
• We may ask to check your UW ID card during the exam so please have it ready.
• You will have 60 minutes to complete the midterm and 110 minutes to complete the final. We will distribute the exam early and you can read and fill out the cover page of the exam, but you should not look at the exam questions until you are told to begin. At the end when time is called, you are required to stop writing and close your exam. Students who look at the exam before being told to begin and students who make changes to their exam after time is called will receive a 10-point penalty. Students who do not close their exam booklet when time is called may also receive a 10-point penalty.
• The exams are closed-book and closed-note. You must work alone and may not use any computing devices of any kind including calculators or digital copies of the textbook. Cell phones, music players, and other electronic devices may NOT be out during the exam for any reason.
• There will be a cheat sheet included as the last page of the exam. Space will be provided for your answers. If you need additional scratch paper, raise your hand and a TA will give it to you. You are not allowed to use your own paper during the exam.
• Unless a question specifically mentions otherwise, the code you write will be graded purely on external correctness (proper behavior and output) and not on internal correctness (style). So, for example, redundancy or lack of comments will not reduce your score. You are, however, required to declare all data fields as private, to use generics properly, and to declare variables and parameters using interfaces when possible. The midterm cheat sheet mentions important restrictions on stacks and queues that you must follow.
• Unless otherwise specified, you should write each solution as a public instance method. You may define helper methods as part of your solution, but they should be declared to be private.
• You are allowed to abbreviate "compiler error" and "runtime error" for the inheritance question on the midterm (as in "ce" and "re" or "c.e." and "r.e."), but you should otherwise NOT use any abbreviations on the exam.
• You don't need to write any import statements in your exam code.
• You are not allowed to use advanced material to solve exam problems. In general, you are restricted to the classes and methods listed on the exam cheat sheet.
• You are not allowed to use break, continue, a return from a void method, try/catch, or Java 8 features.
• For standard Java classes such as Math and String, you are limited to the methods listed on the cheat sheet. You are not allowed to use the Arrays or Collections classes or other standard classes and methods that aren't included on the cheat sheet.
• Please be sure that your answer is clearly indicated. This is particularly important if you provide more than one answer or if you have notes in addition to your answer. You can draw a box around the answer you want to have graded and you can draw an "X" through anything that you do not want to have graded.
• You do not need to turn in scratch paper unless you have all or part of an answer on that sheet of paper (you can take the other sheets of paper with you). If you have a sheet of paper with all or part of an answer, please write your name on that sheet of paper, staple the entire sheet to the end of your test (not in the middle) with a single staple in the upper-left corner, and clearly indicate under the corresponding problem that your answer is attached on an extra sheet of paper. A stapler will be available.
• Please be quiet during the exam. If you have a question or need assistance, please raise your hand.
• When you have finished the exam, please turn in your exam quietly and leave the room.
