This part comprises ten questions. Each question is worth 10 marks. All questions in part 1 will need to be completed.
Prerequisite: Read what an API is in the textbook Introduction to Programming Using Java by David J. Eck on pages 142−143.
When solving the problems in this section, you must follow the application programming interface (API) expected in each problem. You should implement all the attributes and operations mentioned in the API.
Note that there is no main method in the APIs. That is, you should not perform any data processing within the main method. You should rather use the main method to test other methods, prompt the user for some inputs, and display the results returned by your methods.
1. Create a class named AddressBook that has the following field names:
4. A group of AU friends decide to run the Banff, Alberta, Marathon. Their names, times (marathon completion time in minutes), and number of years participated are given below:
Create appropriate get and set methods to retrieve and assign values to these names. For example,
Using the get and set methods, create a comparison method compareNames(name1, name2) that compares the first, middle, and last names of strings name1 and name2. Assume that name1 and name2 follow the following format: “FirstName M. LastName”.
5. Solve the following problem using a program: Suppose you save $100 each month into a savings account with an annual interest rate of 5%. Thus, the monthly interest rate is 0.05/12 = 0.00417.
8. Google Inc. is looking to recruit three of the Boston runners. The criteria for selection are as follows:
I. Average final marks in bachelor’s degree (store up to 2 decimal places). The fifteen candidates have the following grades: 82.30%, 85.10%, 77.77%, 69.93%, 93.03%, 88.61%, 55.99%, 87.49%, 88.00%, 91.20%, 66.79%, 76.65%, 55.89%, 90.01%, and 87.9%.
II. Ability to communicate as one of the three values – “excellent”, “average”, and “poor”. The fifteen candidates have the following ability to communicate, respectively: poor, poor, average, average, average, poor, excellent, excellent, excellent, average, excellent, average, excellent, excellent, poor.
III. Innovation as one of the two values – “brilliant” and “average” (store as a Boolean; brilliant = true and average = false). The fifteen candidates have the following innovative abilities: brilliant, average, average, average, brilliant, brilliant, average, brilliant, average, brilliant, average, brilliant, brilliant, average, average.
IV. Ability to regulate one’s own skill as a probability value between 0 and 1.0 – 1.0 implies excellent regulatory capabilities and 0.0 implies no skills to regulate (store as a double). The fifteen candidates have the following regulatory abilities: 0.5, 1.0, 0.8, 0.0, 1.0, 0.7, 0.8, 0,9, 0.5, 0.6, 0.3, 0.2, 0.5, 0.3, 0.8.
