Modify The Week Three Java Application Using NetBeans 165631
Modify the Week Three Java Application Using Netbeans IDE To Meet These
Modify the Week Three Java application using NetBeans IDE to meet these additional and changed business requirements: The application will now compare the total annual compensation of at least two salespersons. It will calculate the additional amount of sales that each salesperson must achieve to match or exceed the higher of the two earners. The application should ask for the name of each salesperson being compared. The Java application should also meet these technical requirements: The application should have at least one class, in addition to the application's controlling class. The source code must demonstrate the use of Array or ArrayList. There should be proper documentation in the source code.
Paper For Above instruction
This paper presents a comprehensive modification of the Week Three Java application in NetBeans IDE to incorporate new business requirements emphasizing comparative analysis of salespersons’ annual compensation. The enhancements include integrating user input for salesperson details, employing object-oriented concepts with multiple classes, utilizing ArrayList for managing data, and providing thorough code documentation. These modifications aim to improve the application’s functionality, maintainability, and user interaction, aligning with industry standards for software development.
Introduction
The original Java application developed in Week Three primarily focused on core functionalities such as calculating commissions, gross sales, or other sales-related metrics for a single salesperson. However, real-world business scenarios often require comparison and analysis of multiple individuals, especially sales staff, to determine performance standings and compensatory adjustments. Addressing this necessity, the current modification introduces capabilities for comparing multiple salespersons’ total annual compensation, calculating additional sales needed to match top performers, and managing data efficiently. These enhancements necessitate the use of multiple classes, collections, and robust user interaction mechanisms.
Design Overview and Technical Requirements
The modified application is designed with an object-oriented approach, emphasizing clarity, modularity, and reusability. It will include at least two classes: one representing salespersons and another controlling the application's flow and user interaction. The use of ArrayList allows dynamic storage of multiple salesperson objects, enabling scalable comparisons. Documentation within the source code ensures clarity of functionality, aiding future maintenance and understanding.
The application’s core functionalities include:
- Collecting salesperson names and sales data via user inputs.
- Calculating total annual compensation based on sales figures.
- Comparing compensation of multiple salespersons.
- Computing additional sales needed for each salesperson to equate or surpass the top earner.
- Displaying informative results to the user.
This setup ensures an interactive, user-friendly, and analytically robust system.
Implementation Details
The implementation proceeds with defining a `Salesperson` class, encapsulating attributes such as name, total sales, and compensation. This class includes methods to set and get data, as well as perform calculations related to commissions and total compensation. The main controlling class, say `SalesComparison`, handles user input, creation of `Salesperson` objects, storing them in an ArrayList, and performing comparison operations.
The process begins with prompting the user for the number of salespersons to compare. For each salesperson, the program asks for the name and sales data. It then calculates each salesperson's total compensation, perhaps based on a fixed commission rate, and stores each object in the ArrayList. After collecting data, the program determines the highest earner, then calculates the additional sales required for other salespersons to match or exceed this top salary. Results are displayed with clarity, showing each salesperson’s current total compensation and the extra sales needed where applicable.
Sample code snippets illustrate key aspects such as class definitions, data collection, calculations, and output formatting, all documented for clarity.
Sample Source Code with Documentation
```java
// Salesperson.java - Class representing individual salespersons
public class Salesperson {
private String name; // Name of the salesperson
private double totalSales; // Total sales amount
private static final double COMMISSION_RATE = 0.10; // Commission rate of 10%
/**
* Constructor to initialize salesperson with name and sales
* @param name of the salesperson
* @param totalSales amount of sales
*/
public Salesperson(String name, double totalSales) {
this.name = name;
this.totalSales = totalSales;
}
/**
* Calculates total compensation based on sales and commission rate
* @return total compensation
*/
public double getTotalCompensation() {
return totalSales * COMMISSION_RATE; // Assuming only commission as compensation
}
/**
* Estimates additional sales needed to reach target compensation
* @param targetCompensation desired compensation
* @return required additional sales
*/
public double getAdditionalSales(double targetCompensation) {
return (targetCompensation / COMMISSION_RATE) - totalSales;
}
// Getters for name and sales
public String getName() {
return name;
}
public double getTotalSales() {
return totalSales;
}
}
```
```java
// SalesComparison.java - Main class controlling the application flow
import java.util.ArrayList;
import java.util.Scanner;
/**
* The SalesComparison class handles user input, comparisons, and output
*/
public class SalesComparison {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
ArrayList
System.out.print("Enter the number of salespersons to compare: ");
int count = scanner.nextInt();
scanner.nextLine(); // Consume newline character
// Collect data for each salesperson
for (int i = 0; i
System.out.print("Enter name of salesperson " + (i + 1) + ": ");
String name = scanner.nextLine();
System.out.print("Enter total sales for " + name + ": ");
double sales = scanner.nextDouble();
scanner.nextLine();
Salesperson sp = new Salesperson(name, sales);
salespersons.add(sp);
}
// Find highest compensation
Salesperson topEarner = null;
double maxCompensation = 0;
for (Salesperson sp : salespersons) {
double compensation = sp.getTotalCompensation();
if (compensation > maxCompensation) {
maxCompensation = compensation;
topEarner = sp;
}
}
// Display comparison results
System.out.println("\nComparison Results:");
for (Salesperson sp : salespersons) {
System.out.println("Salesperson: " + sp.getName());
System.out.printf("Total Compensation: $%.2f%n", sp.getTotalCompensation());
if (sp != topEarner) {
double neededSales = sp.getAdditionalSales(topEarner.getTotalCompensation());
// Only positive additional sales make sense
if (neededSales > 0) {
System.out.printf("Additional sales needed to match top earner: $%.2f%n", neededSales);
} else {
System.out.println("Already exceeding the top earner's compensation.");
}
} else {
System.out.println("This salesperson has the highest compensation.");
}
System.out.println(); // Blank line for readability
}
scanner.close();
}
}
```
Conclusion
The revised Java application effectively meets all specified business and technical requirements by facilitating the comparison of multiple salespersons’ annual compensation, calculating additional sales required, and utilizing object-oriented principles with collections and documentation. This enhances the application's utility in real-world sales management scenarios, providing insightful data analysis and fostering informed decision-making.
