Midterm Review

The midterm is coming up and to help us study we are creating ten quiz questions that will help us review the material when creating the questions and allow others to review material while scouring for answers. These questions are similar to ones found in class and will test our overall knowledge of the material discussed in class minus anything related to RoboCode.

10 Questions are posted, return on Tuesday for the Answers!

Edited with Answers on the Bottom

Questions

1. Please code the FizzBuzz program discussed at the beginning of the semester. Count from 1-100, replace multiples of 3 with fizz, multiples of 5 with buzz, and multiples of 3 and 5 with FizzBuzz.

2. Why is the above useful knowledge?

3. Why is it useful to ask smart questions? What is an example of a Smart question and answer.

4. Why is it important to know how to override equals() and hashCode()?

5. When overriding equals() and hashCode, what are important things to keep in mind?

6. Why is it important to follow coding standards?

7. How effective is multitasking? Can you list some strategies to be more effective at working?

8. What is ant and how is it a useful tool to us?

9. What are the differences between white box testing and black box testing? Can you give an example where they are used?

10. What is Subversion and Git? What are the differences between them? List an Advantage and Disadvantage of both.

Answers

1. Please refer to your first blog post for the answer.

2. The FizzBuzz program is useful to know because it is a common example of a general coding question that would be asked on an interview.

3. It is useful to ask smart questions because it allows anything who may help you information on the problem and allows them to reply more quickly.

4. It is important to know how to override the two methods because it allows you to change the restrictive method to allow better comparability with objects such as object classes that you define.

5. When override these methods, you must remember to override both of them and that when overriding the equals method it has the following characteristics, Symmetry, Reflexivity, Transitivity, and Consistency.

6. It is important to follow coding standards because it allows uniformity between code and easier accessibility by other users reading and trying to understand your code.

7. Multitasking is not effective, it only feels like we are being more efficient, but it spreads user focus across multiple things and lowers the quality of work. Remove your self from distractions such as cell phones or the TV.

8. Ant is a java build tool that allows us to automate a building process of files in a distribution. It is similar to the make tool, but uses java.

9. White box testing is a more internal approach to testing in which the tests are designed based on the actual code, while black box testing is an external outlook at the testing in which we test to see if the code works correctly.

10. Subversion and Git are version control software. A big difference between the two is that Subversion is centralized and Git is distributed. One advantage of subversion is that when there is a change all the versions will be updated to the most recent, but since it is centralized, everyone will experience problems if the centralized version is compromised. With Git you clone the repository and run and change the files from a local copy off your computer, this means that there is no extra history coming from any other contributor and may lead to having multiple copies a file for different versions.
