JAVA - (The Fan class ) Design a class named Fan to represent a fan. The class contains: Three constants named SLOW, MEDIUM, and FAST with the values 1, 2, and 3 to denote the fan speed. The Fan class VideoNote M08_LIAN6521_09_SE_C08.qxd 2/2/12 10:21 PM Page 331 332 Chapter 8 Objects and Classes A private int data field named speed that specifies the speed of the fan (the default is SLOW). A private boolean data field named on that specifies whether the fan is on (the default is false ). A private double data field named radius that specifies the radius of the fan (the default is 5). A string data field named color that specifies the color of the fan (the default is 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 the fan color and radius along with the string fan is off in one combined string . Draw the UML diagram for the class and then 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 .

SAMPLE RUN:

A 10.0 inch yellow fan at a speed of 3 A 5.0 inch blue fan; fan is off

I posted this already, and someone answered the following, but it prints 1 instead of the.

CURRENT OUTPUT:

1 Yellow 10.0 Blue 5.0 fan is off

NEEDED OUTPUT:

A 10.0 inch yellow fan at a speed of 3 A 5.0 inch blue fan; fan is off

public class Fan {

static final int SLOW = 1; // static final attributes with constant alues static final int MEDIUM = 1; static final int FAST = 1; //Attributes of Fan Class int speed; boolean isFanOnOff; double radius; String color;
