with values of 1, 2 and 3 to denote the headphone volume.
- A private int data field named volume that specifies the volume of
the headphone. The default volume is MEDIUM.

color of the headphones.
- getter and setter methods for all data fields.

- A method named toString() that returns a string describing the
current field values of the headphones.
- A method named changeVolume(value) that changes the
volume of the headphone to the value passed into the method
Create a TestHeadPhone class that constructs at least 3
HeadPhone objects. For each of the objects constructed, demonstrate the use of
each of the methods. Be sure to use your IDE to accomplish this assignment.
