Question

: Consider the following class definition that represents an AM radio

class Radio

{

public bool isSwitchedOn; // either true or false

public int volume; // from 0 to 10

public double frequency; // from 535 to 1605 Mhz

}

Provide a redesigned radio class that uses more appropriate member access operators
Provide signatures for two mutator (setter) methods that will enable the two instance variables to be changed through an object of the class
Write bodies for the mutator (setter) methods for which you provided signatures in question (b), above. The implemented methods must prevent the two instance variables from being set to invalid values. Return a boolean flag to indicate the success/failure of the requested operation
Provide a constructor for the radio class that will initialize the instance variables to suitable (valid) start values.
Write a short test harness that instantiates the radio class and demonstrates that the setter methods you designed above behave correctly
Write a method start that will return true or false depending upon isSwitchedOn.
What should we do if we want to hide method start.
