Q.Answers following points
Association between the Classes 16, Add a mutatormethod to the Forest class that adds a tree object to the class 17. Update the print method from the forest class in such a wav that if a tree obiect is associated, this information is printed as well 18. Add anaccessor method for the forest class that returns the cost of the forest. (hint: data must be fetched from another class) 19. Add an accessor method for the forest class that calculates the revenue of the forest. 20. Add a method that calculated the profit of the forest (revenue - cost)
