The first programming assignment involves writing a program that computes the salaries for a collection of employees of different types. This program consists of four classes. The first class is the Employee class, which contains the employee's name, monthly salary, and year of employment (e.g 2014), which is specified in whole dollars. It should have three methods: 1. A constructor that allows the name, monthly salary, and year of employment to be initialized. 2. A method named annualSalary that returns the salary for a whole year. 3. A toString method that returns a string containing the name, monthly salary, and year of employment appropriately labeled. The Employee class has two subclasses. The first is Salesman. It has an additional instance variable that contains the annual sales in whole dollars for that salesman. It should have the same three methods: 1. A constructor that allows the name, monthly salary, year of employment, and annual sales to be initialized. 2. An overridden method annualSalary that returns the salary for a whole year. The salary for a salesman consists of the base salary computed from the monthly salary plus a commission. The commission is computed as 12% of that salesman's annual sales when annual sales are bigger than or equal to $20,000. There is no sales commission when the annual sales is less than $10,000. The maximum commission a salesman can earn is the monthly salary times 12. 3. An overridden toString method that returns a string containing the name, monthly salary, year of employment, and annual sales, appropriately labeled. The second subclass is Executive. It has an additional instance variable that reflects the current stock price. It should have the same three methods: 1. A constructor that allows the name, monthly salary, year of employment, and stock price to be initialized. 2. An overridden method annualSalary that returns the salary for a whole year. The salary for an executive consists of the base salary computed from the monthly salary plus a bonus. The bonus is $10,000 if the current stock price is greater than $40, $30,000 if the current stock price is greater than $60, and nothing otherwise. 3. An overridden toString method that returns a string containing the name, monthly salary, year of employment, and stock price, appropriately labeled. Finally there should be a fourth class that contains the main method. It should read in employee information from a text file. Each line of the text file will represent the information for one employee for one year. An example of how the text file will look is shown below: 2014 Employee Smith,John 2000 2015 Salesman Jones,Bill 3000 100000 2014 Executive Bush,George 5000 55 The year is the first data element on the line. The file will contain employee information for an arbitrary number of years. You can assume that you do not have more than 100 employees in the file. Next is the type of the employee followed by the employee name and the monthly salary. For salesmen, the final value is their annual sales and for executives the stock price. As the employees are read in, Employee objects of the appropriate type should be created and they should be stored in an array. You may also assume that the data in the file will be formatted correctly. You should not making any assumption about the ordering in that file. Once all the employee data is read in, a report should be displayed on the console for each year, in ascending order of the year. Each line of the report should contain all original data supplied for each employee together with that employee's annual salary for the year. For each year, an average of all salaries for all employees for that year should be computed and displayed. Be sure to follow good programming style, which means making all instance variables private, naming all constants and avoiding the duplication of code. Furthermore you must select enough different kinds of employees to completely test the program. Grading rubrics: 25%: requirements (5% for the completion of each class, 5% for the reading of the data from a file, 5% for printing the results correctly) 20%: test data and test documentation. Have 2 different examples of input files. Describe the expected output for each file in a document, and explain how you computed this expected output, independently of your program; just running your program and pasting the results does not count! Make sure that each test file covers all the requirements. You do not need to include test for correct input. 30%: code structure (use of proper Java constructs, no code repetition, variables as local as possible) 25%: code presentation. Fully spelled and meaningful names (variables, classes, functions), header comment with your full name and the assignment name, no useless comments (in particular the automatically generated comments), no useless imports, proper code indentation. When choosing class name, variable names, make sure to spell out all names, start class names with an uppercase letter, and variable names with lowercase letters, and use the camel notation (class MobilePhone, String phoneNumber for instance). Make sure to clean up generated comments too. To be more specific, make sure that your full name and the actual week and assignment are part of the header comments in your file. Avoid commenting the obvious and make sure that all comments do apply to the work. I do mark down work for comments that are incorrect, do not apply to the file/work, or simply do not explain anything: in particular, auto-generated comments are most likely useless unless you modify them for the purpose of your work. I figured out how to print a report for specific years, but the professor wants it for any year.
