Number 7 and Behavior6. Explain the differences between a field and a parameter. What is the difference in their syntax? What is the differencein 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'sfirst 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 andmutators?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 tothe above method?a. double result = compute Interest (acct, 42);b. acct.compute Interest (42.0, 15);c. int result = BankAccount.compute Interest (42);
