Modify The Week Three Java Application Using NetBeans IDE

Modifythe 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

The evolution of sales management systems necessitates the integration of data comparison features to facilitate strategic sales planning. Building upon the initial Java application implemented in NetBeans IDE during Week Three, this paper addresses the modification of the program to enable comparison of total annual compensation between at least two salespersons. Additionally, it calculates the incremental sales required for each salesperson to match or surpass the higher earner, thereby providing actionable insights for sales performance enhancement. These modifications adhere to specified technical requirements, including object-oriented design principles and the use of data structures.

Introduction

Understanding and optimizing sales performance is critical for business growth. The original Java application encompassed basic sales data input and compensation calculations for a single salesperson. With the need to compare multiple salespersons' compensation and determine necessary sales adjustments, the application demands significant enhancements. This paper discusses the process of modifying the existing Java program within NetBeans IDE, focusing on implementing comparison logic, user-interactive features for input collection, and maintaining code quality through appropriate structure and documentation.

Design Considerations and Class Structures

To meet the requirement of having at least one additional class apart from the main controlling class, a dedicated class named `Salesperson` is created. This class encapsulates attributes such as name, annual sales, and total compensation, as well as methods to perform calculations. The main class, `SalesApplication`, handles user input, manages an ArrayList of `Salesperson` objects, and performs comparisons. Using ArrayList enables flexible storage for multiple salesperson objects and simplifies iterative processing.

The `Salesperson` class features include:

- Private fields for name, annual sales, compensation, and computed sales needed.

- Constructor for initializing objects.

- Methods for computing total compensation and the sales needed to match a higher earner.

- Getters for retrieving attribute data, facilitating encapsulation.

Implementation Details

Using NetBeans IDE, the application begins by prompting the user to enter the number of salespersons to compare, followed by iteratively collecting each salesperson's name and annual sales figures. Each input creates a `Salesperson` object added to an ArrayList.

Once data collection concludes, the program determines the top earner by comparing total compensation values. It then iterates through the list of `Salesperson` objects to calculate how much additional sales each needs to match the top earner's compensation. These calculations involve determining the difference in compensation and translating it into incremental sales using the compensation-per-unit-sold ratio.

The modified program includes comprehensive prompts and output results clearly stating each salesperson's needed sales to reach or surpass the highest earner's compensation. This feature directly supports strategic decision-making and motivates salespersons towards targeted goals.

Technical Implementation

1. Data input and object creation

```java

Scanner scanner = new Scanner(System.in);

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

int numberOfSalespersons = scanner.nextInt();

ArrayList salespersons = new ArrayList();

for (int i = 0; i

System.out.print("Enter name of salesperson " + (i + 1) + ": ");

String name = scanner.next();

System.out.print("Enter annual sales for " + name + ": ");

double sales = scanner.nextDouble();

salespersons.add(new Salesperson(name, sales));

}

```

2. Calculations and comparisons

```java

Salesperson topEarner = Collections.max(salespersons, Comparator.comparing(Salesperson::getTotalCompensation));

System.out.println("Top compensation is earned by: " + topEarner.getName()

+ " with $" + topEarner.getTotalCompensation());

for (Salesperson sp : salespersons) {

if (sp != topEarner) {

double neededCompensation = topEarner.getTotalCompensation() - sp.getTotalCompensation();

double salesNeeded = sp.calculateSalesNeeded(neededCompensation);

System.out.println(sp.getName() + " needs to increase sales by $" + salesNeeded

+ " to match or exceed the top earner's compensation.");

}

}

```

3. Salesperson class structure

```java

public class Salesperson {

private String name;

private double annualSales;

private final double commissionRate = 0.10; // For example, 10% commission

public Salesperson(String name, double annualSales) {

this.name = name;

this.annualSales = annualSales;

}

public String getName() {

return name;

}

public double getTotalCompensation() {

// Assuming fixed base salary plus commission

double baseSalary = 30000; // Example base salary

return baseSalary + (annualSales * commissionRate);

}

public double calculateSalesNeeded(double additionalCompensation) {

return additionalCompensation / commissionRate;

}

}

```

Conclusion

The modifications align the Java application with the new business and technical requirements. By integrating object-oriented design through the `Salesperson` class, employing ArrayList for dynamic data management, and implementing logic for comparing compensation and calculating sales needed, the program offers practical utility for sales performance analysis. This enhancement promotes data-driven decision-making and contributes to strategic sales planning.
