Exam 6: A First Look at Classes

A method that gets a value from a class's field but does not change it is known as a mutator method.

It is common practice in object-oriented programming to make all of a class's:

The public access specifier for a field indicates that the attribute may not be accessed by statements outside the class.

The following package is automatically imported into all Java programs.

When an object is passed as an argument to a method, what is passed into the method's parameter variable?

When an object is created, the attributes associated with the object are called:

In UML diagrams, this symbol indicates that a member is public.

An access specifier indicates how the class may be accessed.

When you are working with a ________, you are using a storage location that holds a piece of data.

A method that stores a value in a class's field or in some other way changes the value of a field is known as a mutator method.

In the cookie cutter metaphor, think of the ________ as a cookie cutter and ________ as the cookies.

Given the following code, what will be the value of finalAmount when it is displayed? Public class Order { Private int orderNum; Private double orderAmount; Private double orderDiscount; Public Order(int orderNumber, double orderAmt, Double orderDisc) { OrderNum = orderNumber; OrderAmount = orderAmt; OrderDiscount = orderDisc; } Public double finalOrderTotal() { Return orderAmount - orderAmount * OrderDiscount; } } Public class CustomerOrder { Public static void main(String[] args) { Order order; Int orderNumber = 1234; Double orderAmt = 580.00; Double orderDisc = .1; Order = new Order(orderNumber, orderAmt, orderDisc); Double finalAmount = order.finalOrderTotal(); System.out.printf("Final order amount = $%,.2f\n", FinalAmount); } }

What is stored by a reference variable?

The term "default constructor" is applied to the first constructor written by the author of a class.

Data hiding, which means that critical data stored inside the object is protected from code outside the object, is accomplished in Java by:

Most programming languages that are in use today are:

A constructor:

Instance methods should be declared static.
