We want to realize a program for managing the fund-raising activities of volunteers working in a no-profit organization. For each volunteer, the following information is stored:

• name (a string),
• bonus (in percent) granted by the Province (a double),
• amount of money that the volunteer has collected (a double),

Part 1. Write a class Volunteer that implements the following methods:

• Volunteer(String name) : constructor that creates an object representing a volunteer whose name is name, whose initial bonus is 0, and whose initial amount of money is 0.
• String getName() : that returns the name of the volunteer;
• double getBonus() : that returns the bonus of the volunteer.
• double getAmount() : that returns the amount of money collected by the volunteer;
• void collect(double m) : that increases the amount of money collected by the volunteer by m; if m is greater than or equal to 1000, then the bonus is increased by 1 (percent).
• void spend(double m) : that decreases the amount of money collected by the volunteer by m, if m is smaller or equal than the amount of money collected, and otherwise does nothing.
• void useBonus() : that increases the amount of money collected by the volunteer by the percentage specified by the bonus, and sets then the bonus to 0.
• String toString() : that returns a string with all the information about the volunteer.

Example program: TestVolunteer.Java

Part 2. Write a class UseVolunteer, client of Volunteer, that contains the following public static method:

• static double totalAmount(Volunteer v1, Volunteer v2) : that, given two volunteers v1 and v2, calculates and returns the sum of the amount of money raised by the two volunteers, considering also the bonuses.
  • If both volunteers have a positive bonus, the maximum bonus among those of v1 and v2 is applied to the sum of the money raised by v1 and v2.
  • If only one of the two volunteers has a positive bonus (and the other one has bonus 0), then the positive bonus is applied only to the money of that volunteer.
  • If both volunteers have a bonus of 0, then no bonus is applied.
