Answer:
Logic Classes
Explanation:
There are three classes in a three-tiered architecture, which are:
1) Presentation classes
2) Logic Classes
3) Data Classes
Hence, the middle layer is the Logic classes.
Answer:
C. consistency, aesthetics
Explanation:
Based on the descriptions given to us in the question we can deduce that the answer is C. consistency, aesthetics. This is because "consistency" is defined as something that always delivers the same results, which is what users need from the interface in order to understand it and continue using it. While "aesthetics" is defined as the visual representation of something (how something will look).

Answer:
- import java.util.Scanner;
- public class MealPriceCalculation{
-
- public static void main(String[] args) {
-
- Scanner input = new Scanner(System.in);
- System.out.print("Enter meal price: ");
- double meal = input.nextDouble();
- System.out.print("Enter tip: ");
- double tip = input.nextDouble();
-
- calculatePrice(meal,tip);
- calculatePrice(meal,(int)tip);
-
- }
-
- public static void calculatePrice(double meal, double tip){
- System.out.println("Total meal price: $" + (meal + tip) );
- }
-
- public static void calculatePrice(double meal, int tip){
- System.out.println("Total meal price $" + (meal+tip));
- }
- }
Explanation:
The solution code is written in Java.
Overload methods are the methods that share the same name but with different method signature. In this question, we create two overload methods calculatePrice (Line 17-23). One version will accept parameter meal and tip in double type and another will accept parameter meal in double but tip in integer. Both of this method are doing the same job which is just printing the total of meal.
In the main program, create a Scanner object and use it to prompt user to input meal price and tip (Line 6-10). Next call the calculatePrice method for twice. In the first time, pass meal and tip as double type data to calculatePrice method (Line 12). In the second time, pass meal in double but tip in integer to the method. Only the method with parameter list that match the argument data type will be implemented and output the total meal price.
To calculate amount needed we use the following formula:
![2^{a} \cdot b](https://tex.z-dn.net/?f=%202%5E%7Ba%7D%20%5Ccdot%20b%20)
Where a - number of input bits
b - number of output bits
In this case we have:
![2^{4} \cdot 2^{4} = 2^{8} = 256](https://tex.z-dn.net/?f=%202%5E%7B4%7D%20%5Ccdot%202%5E%7B4%7D%20%3D%202%5E%7B8%7D%20%3D%20256%20)
input bits
The number of output bits would be 8.
