Question 4 Map Collections

Consider the following class fragment for an Employee class:

class Employee {

private String employeeID;

private boolean isManager;

public String getEmployeeID() { return employeeID; }

public boolean getIsManager() { return isManager; }

// ...

}

You are writing code for a Human Resources Management System for your

company. The company has performed very badly over the past year, and

as a result, every employee's salary is being docked by 10%, unless they are

a manager - in which case their salary is increased by 10%. Write the

method adjustSalaries, for which a skeleton is given below. If you need

to make any assumptions, you should state them in a comment in your

code.

/** Adjusts employee salaries down by 10%, unless the employee

* is a manager, in which the salary is increased by 10%.

*

* @param employeeSalaries A map from an Employee object, to an

* Integer representing their salary (in dollars).

*/

public void adjustSalaries(HashMap employeeSalaries) {

// ...

}
