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

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;
  

//Constructor which stores default values
public Fan(){
speed = 0;
isFanOnOff = false;
radius = 0.0;
color = "";
}
  

// toString method used to return String data of Fan
public String toString(){
if(isFanOnOff){ // Checking Whether Fan is on/off
return this.getSpeed()+" "+this.getColor()+" "+this.getRadius();
}else{
return this.getColor()+" "+this.getRadius()+" "+" fan is off";
}
}

//Setters and Getters of Attributes defined earliier
public int getSpeed() {
return speed;
}

public void setSpeed(int speed) {
this.speed = speed;
}

public boolean isFanOnOff() {
return isFanOnOff;
}

public void setFanOnOff(boolean isFanOnOff) {
this.isFanOnOff = isFanOnOff;
}

public double getRadius() {
return radius;
}

public void setRadius(double radius) {
this.radius = radius;
}

public String getColor() {
return color;
}

public void setColor(String color) {
this.color = color;
}

public static void main(String[] args) {
Fan fan1 = new Fan(); //Creating Fan object1
fan1.setSpeed(Fan.FAST);
fan1.setRadius(10);
fan1.setColor("Yellow");
fan1.setFanOnOff(true);
  
System.out.println(fan1.toString());
  
Fan fan2 = new Fan(); //Creating Fan object2
fan2.setSpeed(Fan.MEDIUM);
fan2.setRadius(5);
fan2.setColor("Blue");
fan2.setFanOnOff(false);
  
System.out.println(fan2.toString());

}

}

   String color="blue";
  
   //Constructor which stores default values
   public Fan(){
   speed = 0;
   isFanOn = false;
   radius = 0.0;
   color = "";
   }
  
   // toString method used to return String data of Fan
   public String toString(){
       String onOrOff;
       if(isFanOn())
      ;
       else
      ;
         
   if(isFanOn){ // Checking Whether Fan is on/off
   return "A "+this.getRadius()+" inch "+this.getColor()+" fan at a speed of "+this.getSpeed();
   }else{

   }
   public void setSpeed(int speed) {
   this.speed = speed;
   }
   public boolean isFanOn() {

   return isFanOn;
   }
   public void setFanOn(boolean isFanOn) {

   fan1.setColor("Yellow");
   fan1.setFanOn(true);
  
   System.out.println(fan1.toString());
  
   Fan fan2 = new Fan(); //Creating Fan object2
   fan2.setSpeed(Fan.MEDIUM);
   fan2.setRadius(5);
   fan2.setColor("Blue");
   fan2.setFanOn(false);
  
   System.out.println(fan2.toString());
   }
   }
