Personal Trainer, Inc. owns and operates fitness centers in a dozen Midwestern cities. The centers have done well, and the company is planning an international expansion by opening a new "supercenter" in the Toronto area. Personal Trainer’s president, Cassia Umi, hired an IT consultant, Susan Park, to help develop an information system for the new facility. During the project, Susan will work closely with Gray Lewis, who will manage the new operation.
Background
Susan and Gray finished their work on user interface, input, and output design. They developed a user-centered design that would be flexible and easy to learn. Now Susan turned her attention to the architecture for the new system. Susan wanted to consider their own organization and culture, enterprise resource planning, total cost of ownership, scalability, Web integration, legacy systems, processing methods, security issues, and corporate portal. She also needed to select a network plan, or topology, that would dictate the physical cabling and network connections, or consider a wireless network. When all these tasks were completed, she would submit a system design specification for approval.
Tasks
1. What software and hardware infrastructure will be necessary to ensure Personal Trainer can process point of sale transactions?
2. Prepare an outline for a system design specification and describe the contents of each section.

import java.util.Scanner;
public class PaintClculator {
public static void main(String[] args) {

double length = in.nextDouble();

double price = price(noGallons);
System.out.println("Price is: "+ price);
}
// Creating Method to Calculate Wall Area
public static double calculateWallArea( double length, double width, double height){
// formular for the surface area of a room Area=2*length*heigth+2*width*height+lenth*width
double Area = 2*length*height+2*width*height+length*width;
System.out.println("Wall Area: "+Area);
return Area;
}
//Creating method to calculate amount of paint
public static double calculatePaint(double Area){
double noGallons = Area/350;
System.out.println("Number of gallons: "+noGallons);
return noGallons;
}
// Creating Method Calculate Price
public static double price(double noGallons){
return noGallons*32;
}
}
Explanation
Created Three Methods in all; calculateWallArea(), calculatePaint(), and price()Method calculateWallArea() calculates area based on this formula Area=2*length*heigth+2*width*height+lenth*widthThe value of Area is passed to method calculatePaint() Which calculates the number of gallons required to cover the area given that one gallon covers 350 wall spaceMethod price() calculates and dis[plays the price by calling method calculatePaint() that returns number of gallons. since one gallon is 32$
