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

■ A private int data field named speed 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 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
