a program that computes the salaries for a collection of employees of different types

Solution is attached as zip fileInstructions

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 Employee class,
which contains the employee's name and monthly salary, which is specified in
whole dollars. It should have three methods:

A constructor that allows the name and monthly salary to be
initialized.

A method named annualSalary that returns the salary for a
whole year.

A toString method that returns a string containing the name
and monthly salary, 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:

A constructor that allows the name, monthly salary and
annual sales to be initialized.

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 2% of that salesman's annual sales. The maximum commission a salesman can
earn is $20,000.

An overridden toString method that returns a string
containing the name, monthly salary 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:

A constructor that allows the name, monthly salary and stock
price to be initialized.

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 $30,000 if the
current stock price is greater than $50 and nothing otherwise.

An overridden toString method that returns a string
containing the name, monthly salary 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 only two years: 2014 and 2015. 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 one of two arrays depending
upon the year. You may assume that the file will contain no more than ten
employee 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 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
