Having sound enhances your App, do you agree with this? Explain.
Ksenya-84 [330]

Answer:

Yes, it does.

Explanation:

I mean, having some sort of audio feedback is obviously useful for a user.

(If it's a media-content-viewer, of course you need sound)

We should discuss some cases here:

1. In case it's a game, sound enhances the experience of the virtual world, by creating what is called an "ambience", or the acoustical surroundings of the environment since you can perceive stuff without the need to look at it.

2. Other apps: It makes the app seem more friendly and comfortable to use, especially if partnered with an animation

  double priceF, priceS, priceT;

  int nOne = 0, nTwo = 0, nThree = 0;

  int fBurn, sBurn, tBurn;

  int burnTime = 0;

  isEnd = "n";

   while (isEnd == "n"){

      Scanner in = new Scanner(System.in);

      int option = in.nextInt();

      if (option == 1){

            priceF = 2.50;

            fBurn = 5;

            System.out.print("Enter number of items: ");

            nOne += in.nextInt();

            burnTime += fBurn * nOne;

            cost += priceF * nOne;

        } else if (option== 2){

            priceS = 3.75;

            sBurn = 7;

            System.out.print("Enter number of items: ");

            nTwo += in.nextInt();

            burnTime += sBurn * nTwo;

            cost += priceS * nTwo;

        } else if(option == 3){

            priceT = 5.99;

            tBurn = 12;

            System.out.print("Enter number of items: ");

            nThree += in.nextInt();

            burnTime += tBurn * nThree ;

            cost += priceT * nThree;

        } else{

            System.out.println("option must be between 1 and 3");

        }

      System.out.print("Do you want to end the order? y/n: ");

      isEnd = in.nextLine();

  }

  System.out.println("Number of Type 1 candles bought : "+nOne);

  System.out.println("Number of Type 2 candles bought : "+nTwo);

  System.out.println("Number of Type 3 candles bought : "+nThree);

  System.out.println("Total cost is : "+cost);

  System.out.println("Total burn time is : "+burnTime);

  double cpm = (burnTime * 60) / cost;

  System.out.println("Cost per minute : "+cpm);

}

}

Explanation:

The Java program prompts the user to continuously choose from three options 1, 2 and 3. The prices, the burn time and the cost per minute burn of the total candles ordered are printed out.
