The first programming project 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 class, which contains the employee’s name and monthly salary, which is specified in whole dollars. It should have three methods: The class has two subclasses. The first is . It has two additional instance variables that contains the annual sales in whole dollars for that employee, and the commission rate. It should have the same three methods: The second subclass is . It has an additional instance variable that reflects the current stock price. It should have the same three methods: 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: The year is the first data element on the line. The file will contain employee information for only two years: 2014 and 2015. Next is the type of the employee followed by the employee name and the monthly salary. For employees on commission, the final value is their annual sales and for executives the stock price. As the employees are read in, objects of the appropriate type should be created and they should be stored in one of two arrays depending upon the year. You may assume that the file will contain no more than ten empl
oyee records for each year and that the data in the file will be formatted correctly. Once all the employee data is read in, a report should be displayed on the console for each of the two years. 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 of the two years, 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 , naming all constants and avoiding the duplication of code. Furthermore you must select enough different kinds of employees to completely test the program. 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, just running your program and pasting the results does not count! 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.
