1- 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. The default values are 1 for both width and height. ? A no-arg constructor that creates a default rectangle. ? A constructor that creates a rectangle with the specified width and height. ? A method named getArea() that returns the area of this rectangle. ? A method named getPerimeter() that returns the perimeter. Draw the UML diagram for the class. Implement the class. Write a test program that creates two Rectangle objects-one with width 4 and height 40 and the other with width 3.5 and height 35.9. Display the width, height, area, and perimeter of each rectangle in this order. 2- Design a class named Fan to represent a fan. The class contains: ? Three constants named SLOW, MEDIUM, and FAST with values 1, 2, and 3 to denote the fan speed. ? A private int data field named speed that specifies the speed of the fan (default SLOW).Page 2 of 2 ? A private boolean data field named on that specifies whether the fan is on (default false). ? A private double data field named radius that specifies the radius of the fan (default 5). ? A string data field named color that specifies the color of the fan (default blue). ? The accessor and mutator methods for all four data fields. ? A no-arg constructor that creates a default fan. ? A method named toString() that returns a string description for the fan. If the fan is on, the method returns the fan speed, color, and radius in one combined string. If the fan is not on, the method returns fan color and radius along with the string "fan is off" in one combined string. Draw the UML diagram for the class. Implement the class. Write a test program that creates two Fan objects. Assign maximum speed, radius 10, color yellow, and turn it on to the first object. Assign medium speed, radius 5, color blue, and turn it off to the second object. Display the objects by invoking their toString method.
