Question

Convert the ProjectedRaises class to an interactive application named ProjectedRaisesInteractive. Instead of assigning values to the salaries, accept them from the user as input.

Answer 1

To convert the ProjectedRaises class to an interactive application, you need to utilize Java's Scanner class to accept user input for salaries and then compute and output the projected raises.

Step-by-step explanation:

The question relates to converting a non-interactive Java class, presumably called ProjectedRaises, into an interactive application named ProjectedRaisesInteractive. In the interactive version, the application will accept user input instead of having predefined salary values. This typically involves using Java's Scanner class or similar to capture user input from the console. Once the salaries are input by the user, the application will likely perform calculations, such as determining the projected raises, and then output the results back to the user.

Here's a simple outline of steps you might follow to create the interactive application:

• Import the Scanner class.
• Create a Scanner instance to read input from System.in.
• Prompt the user for current salary figures.
• Read the salaries using the Scanner instance.
• Compute the raises and new salaries.
• Output the results to the console.

By following these steps, the student can create a Java application that not only calculates projected raises but also engages with the user by requesting and receiving input dynamically.

Answer 2

To convert the ProjectedRaises class to an interactive application, you can use a Scanner object to accept salary values from the user. Then, calculate the projected raises and new salaries using the input values, and display the new salaries.

Step-by-step explanation:

To convert the ProjectedRaises class to an interactive application, we need to accept salary values from the user as input instead of assigning them in the code. Here's how you can do it:

Create a Scanner object to read input from the user.

Prompt the user to enter the salaries, and use the Scanner object to read and store them in variables.

Calculate the projected raises and new salaries using the same logic as before.

Display the new salaries to the user.

Here's an example of the code:

import java.util.Scanner;

public class ProjectedRaisesInteractive {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);

System.out.println("Enter the first salary:");
double salary1 = scanner.nextDouble();

System.out.println("Enter the second salary:");
double salary2 = scanner.nextDouble();

// Calculate projected raises and new salaries
double raise1 = salary1 * 0.04;
double raise2 = salary2 * 0.04;

double newSalary1 = salary1 + raise1;
double newSalary2 = salary2 + raise2;

// Display the new salaries
System.out.println("New salary for employee 1: " + newSalary1);
System.out.println("New salary for employee 2: " + newSalary2);
}
}
