Hey guys looking for some Java help

click on one of our sponsors! OR REMOVE ADS

Im coding this application and I cant figure out how to make the last bit to work. It asks for user input in a loop until they do not want to input any more entries, it should then use the entered data to calculate a total and averages.

From what i have it just uses the last entry from the loop and not the entire loop. Any help would be appreciated, thanks!

To sum up the program will:
* Ask whether the consultant is a partner (y/n)
* Asks for employee hours
* Calculate the total cost for the employee
* Output the Employee type, Employee Hours and Employee Cost
* Repeat if desired
Then it will: (heres where im having trouble)
*Tabulate the total number of employees
* Tabulate the total project cost
* Calulate the average hours per employee
* Calculate the average project hourly billing rate
and output it to the console.

Code:

import java.text.NumberFormat;
import java.util.Scanner;

public class BillingAppp
{
    public static void main(String[] args)
	{
        // welcome the user to the program
        System.out.println("Weclome to the Billing Application");
        System.out.println();  // print a blank line
		final double PARTNER_RATE = 300.00;
		final double REGULAR_RATE = 150.00;
		double employeeRate = 0;
		int employeeCount = 0;
		double payRate = 0.0;
		double totalCost = 0.0;
		double workHours = 0.0;
		double averageBilling = 0.0;
		double averageHours = 0.0;
		String employeeType = "employeeType";

		// create a Scanner object named sc
				Scanner sc = new Scanner(System.in);
		        String choice = "y";
        		while (!choice.equalsIgnoreCase("n"))
        {
			// get the input from the user declaring which consultant and assigns string and rate
	           System.out.print("Is the consultant a partner?: (y/n)  ");
	           choice = sc.next();
				employeeCount = employeeCount + 1;
				if (choice.equals("y") || choice.equals("Y"))
				payRate = PARTNER_RATE;
				if (choice.equals("y") || choice.equals("Y"))
				employeeType = "Partner Consultant";
				if (choice.equals("n") || choice.equals("N"))
				payRate = REGULAR_RATE;
				if (choice.equals("n") || choice.equals("N"))
				employeeType = "Regular Consultant";

	            System.out.print("Enter Employee Hours: ");
			    workHours = sc.nextDouble();
	        	System.out.println();

			 //calculate total cost
			 	averageHours = workHours / employeeCount;
				averageBilling = totalCost / employeeCount;
			 	totalCost = (payRate * workHours);
				NumberFormat currency = NumberFormat.getCurrencyInstance();
        	   	System.out.println(
				        	    "Employee Type: " + employeeType + "\n" +
				        	    "Employee Hours: " + (workHours) + "\n" +
        					    "Total Employee Cost: " + currency.format(totalCost) + "\n");
        					     System.out.println();


				// see if the user wants to add another employee
			        	System.out.print("Do you want to add another employee? (y/n): ");
						choice = sc.next();
        				System.out.println();

				}

        		// calculate and display total number of employees, total project cost, avg hours worked, avg billing rate
							NumberFormat currency = NumberFormat.getCurrencyInstance();
							String message = "Total number of Employees: " + employeeCount + "\n"
							             + "Total Project Cost:    " + currency.format(totalCost) + "\n"
							             + "Average Hours Worked : " + (averageHours) + "\n"
							             + "Average Billing Rate:  " + currency.format(averageBilling) + "\n";
													System.out.println(message);

		}
}

I need to have a set of variables that are used for each individual employee, and then a set of overall variables that track all the various totals. But I cant figure out how to set that part up.

I'm sure this is what you ment to do. I created an additional variable called employeeCost which is added to totalCost at the end of each while loop. And I moved averageHours and averageBilling out of the loop. Like I said, I did not compile this, good luck. Code: import java.text.NumberFormat; import java.util.Scanner; public class BillingAppp { public static void main(String[] args) { // welcome the user to the program System.out.println("Weclome to the Billing Application"); System.out.println(); // print a blank line final double PARTNER_RATE = 300.00; final double REGULAR_RATE = 150.00; double employeeRate = 0; int employeeCount = 0; double payRate = 0.0; double employeeCost = 0.0; double totalCost = 0.0; double workHours = 0.0; double averageBilling = 0.0; double averageHours = 0.0; String employeeType = "employeeType"; // create a Scanner object named sc Scanner sc = new Scanner(System.in); String choice = "y"; while (!choice.equalsIgnoreCase("n")) { // get the input from the user declaring which consultant and assigns string and rate System.out.print("Is the consultant a partner?: (y/n) "); choice = sc.next(); employeeCount = employeeCount + 1; if (choice.equalsIgnoreCase("y")) { payRate = PARTNER_RATE; employeeType = "Partner Consultant"; } else if (choice.equalsIgnoreCase("n")) { payRate = REGULAR_RATE; employeeType = "Regular Consultant"; } System.out.print("Enter Employee Hours: "); workHours = sc.nextDouble(); System.out.println(); //calculate the employees cost, and print employeeCost = (payRate * workHours); NumberFormat currency = NumberFormat.getCurrencyInstance(); System.out.println( "Employee Type: " + employeeType + "\n" + "Employee Hours: " + (workHours) + "\n" + "Total Employee Cost: " + currency.format(employeeCost) + "\n"); System.out.println(); totalCost = totalCost + employeeCost; // see if the user wants to add another employee System.out.print("Do you want to add another employee? (y/n): "); choice = sc.next(); System.out.println(); } //end while // calculate and display total number of employees, total project cost, avg hours worked, avg billing rate averageHours = workHours / employeeCount; averageBilling = totalCost / employeeCount; NumberFormat currency = NumberFormat.getCurrencyInstance(); String message = "Total number of Employees: " + employeeCount + "\n" + "Total Project Cost: " + currency.format(totalCost) + "\n" + "Average Hours Worked : " + (averageHours) + "\n" + "Average Billing Rate: " + currency.format(averageBilling) + "\n"; System.out.println(message); } //end main } //end class
