Write a complete Java program to do the following.
The attributes of a TV object are the channel, the
volume, and the flag (or switch) indicating the
channel No., volume level and whether the TV is on
or off respectively. Use appropriate datatypes for the
data members.
The methods of the class perform the following
actions:
• Turn the TV on or off ( Toggling)
• Set the channel to an integer in the range 0 to 99 ,
inclusive of both lower and upper limits.
• Raise or lower the volume by one unit. The volume
can range from 0 to 20. (Inclusive of both lower and
upper limits. Include conditions to check the range)
display method displays the following
i) whether the TV is on or off.
ii) channel volume.
iii) channel number
Write a TV class containing the required instance
variables (private) and all relevant methods and a
constructor. A newly created TV object is set to off
with the channel set to 2 and the initial volume 10.
Keep TV class in mypacks package. Write a Driver
class to include a main...) method that tests the
methods of the TV class by creating array of TV
objects
