    (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

    ■ 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 .
