Number 8
and Behavior 6. Explain the differences between a field and a parameter. What is the difference in their syntax? What is the difference in their scope and the ways in which they may be used? 7. Create a class called Name that represents a person's name. The class should have fields representing the person's first name, last name, and middle initial. (Your class should contain only fields for now.) 8. What is the difference between an accessor and a mutator? What naming conventions are used with accessors and mutators? 9. Suppose we have written a class called BankAccount with a method inside it, defined as: public double compute Interest (int rate) If the client code has declared a BankAccount variable named acct, which of the following would be a valid call to the above method? a. double result = compute Interest (acct, 42); b. acct.compute Interest (42.0, 15); c. int result = BankAccount.compute Interest (42);
