Question

using visual studios C# implementing using system; be sure I can copy and paste. Exercise #2: Design and implement class Radio to represent a radio object. The class defines the following attributes (variables) and methods: Assume that the station and volume settings range from 1 to 10. 1. A private variable of type int named station to represent a station number. Set to 1. 2. A private variable of type int named volume to represent the volume setting. Set to 1. 3. A private variable of type boolean named on to represent the radio on or off. Set to false. 4. A non-argument constructor method to create a default radio. 5. Method getStation() that returns the station. 6. Method getVolume() that returns the volume. 7. Method turnOn() that turns the radio on. 8. Method turnOff() that turns the radio off. 9. Method stationUp() that increments the station by 1 only when the radio is on. 10. Method stationDown() that decrements the station by 1 only when the radio is on. 11. Method volumeUp() that increment the volume by 1 only when the radio is on. 12. Method volumeDown() that decrements the volume by 1 only when the radio is on. 13. Method toString()to printout a meaningful description of the radio as follows(if the radio is on): The radio station is X and the volume level is Y. Where X and Y are the values of variables station and volume. If the radio is off, the message is: The radio is off. Now design and implement a test program to create a default radio object and test all class methods on the object in random order. Print the object after each method call and use meaningful label for each method call as shown in the following sample run.

Answer 1

Hi, PFA for the sample run

Please find below the code for the implementation of the same:

using System;

public class Program
{
   public static void Main()
   {
       Radio radioObj = new Radio();
       radioObj.toString();
       radioObj.volumeDown();
       radioObj.turnOn();
       radioObj.toString();
       radioObj.stationUp();
       radioObj.toString();
       radioObj.volumeUp();
       radioObj.toString();
       radioObj.volumeDown();
       radioObj.toString();
       radioObj.turnOff();          
   }
}
public class Radio
{
   private int station;
   private int volume;
   private bool isRadioTurnedOn;
  
   public Radio()
   {
       this.station = 1;
       this.volume=1;
       this.isRadioTurnedOn=false;
   }
   public int getStation()
   {
       return this.station;
   }
   public int getVolume()
   {
       return this.volume;
   }
   public void turnOn(){
       this.isRadioTurnedOn = true;
   }
   public void turnOff(){
       this.isRadioTurnedOn = false;
   }
   public void stationUp(){
       if(this.isRadioTurnedOn && this.station<10){
           this.station = this.station+1;
       }
       else{
           Console.WriteLine("Unable to Up the station as the radio is "+ (this.isRadioTurnedOn?"On":"Off") + " and station in "+this.station);
       }
   }
   public void volumeUp(){
       if(this.isRadioTurnedOn && this.volume<10){
           this.volume = this.volume+1;
       }
       else{
           Console.WriteLine("Unable to Up the Volume as the radio is "+ (this.isRadioTurnedOn?"On":"Off") + " and volume in "+this.volume);
       }
   }
   public void stationDown(){
       if(this.isRadioTurnedOn && this.station>1){
           this.station = this.station-1;
       }
       else{
           Console.WriteLine("Unable to Down the station as the radio is "+ (this.isRadioTurnedOn?"On":"Off") + " and station in "+this.station);
       }
   }
   public void volumeDown(){
       if(this.isRadioTurnedOn && this.volume>1){
           this.volume = this.volume-1;
       }
       else{
           Console.WriteLine("Unable to Down the Volume as the radio is "+ (this.isRadioTurnedOn?"On":"Off") + " and volume in "+this.volume);
       }
   }
   public void toString()
   {
       if(this.isRadioTurnedOn)
       {
           Console.WriteLine("The radio station is {0} and the volume level is {1}.", this.getStation(), this.getVolume());
       }
       else
       {
           Console.WriteLine("Please turn on the radio!!!");
       }
   }

}
