chapter 9

LRCISES Pedagogical Note three ob The exercises achieve three objectives: 1. Design and draw UML for classes: 2. Implement classes from the UML: 3. Use classes to develop applications. Solutions for the UML diagrams for the even-numbered exercises can be downloaded from the Companion Website and all others from the Instructor Web site. Sections 9.2-9.11 9.1 (The Rectangle class) Design a class named Rectangle to represent a rectangle, The class contains: Two double data fields named width and height that specify the width and height of the rectangle. Ano-arg constructor that creates a rectangle with width 1 and height A constructor that creates a default rectangle with the specified width and height. The accessor and mutator functions for all the data field A function named getArea() that returns the area of this rectangle. A function named getPerimeter that returns the perimeter Implement the class. Write a test program Draw the UML diagram for the class. Implement the class. Writ nale objects. Assign width 4 and height 40 to the first that creates two Rectangle objects. Assign width 4 and her sht 35.9 to the second. Display the properties of both object and width 3.5 and height 35.9 to the second. Display the objects and find their areas and perimeters
