Does anyone know Java?

This is what I have to do

Your neighbor’s teenage son currently cuts your yard every ten days. Your beautiful front yard is a perfect rectangle, with the street measurement being 48 feet and the driveway side being 32 feet. Your current cost to have it fully cut and manicured is $50.50 every ten days. A new lawn service will do the same job for $0.30 per square yard, with an 8% discount, if you agree to allow them to do your yard for 9 consecutive times. You are to write a Java program to determine which one is the best deal. Now adapt your program to allow you to input values at runtime for any yard in your property portfolio. See additional notes below:

• Total feet (area) of the yard must be converted to square yards for calculation purposes. A Google search for "calculate area of rectangle" and "feet to square yards conversion" will provide the necessary information. There a several ways you might setup your calculations.

• The data types chosen will potentially have a slight affect on the results. The sample output assumes that the street measurement (width), driveway measurement (length), area of the yard, and square yardage are whole numbers; while the lawn service price, lawn service discount, and discounted lawn service price are floating-point values

• Give careful consideration on how named constants can be incorporated into your program for current cost, lawn service cost per square yard, and discount rate; all are assumed to be floating-point values

• It is not necessary to format for a particular number of decimal places at this time or for the dollar sign symbol, $, which is simply embedded in the character string of the print statement

This is what I have so far and I seriously don't know if any of it is right. I am basing it off an example program we did that is doing a similar thing.

Spoiler

import javax.swing.JOptionPane;

public class SmithK_Lab02

{
	public static void main(String[] args)
	{

		//declare variables

		double squareYards;
		double areaFeet;
		double length;
		double width;
		double costSqyd;
		double costTeen;
		double costCompany;
		double discountRate;
		double dicountedPrice;
		double timesMowed;
		String inputValue;


	//assign numbers to the variables

	inputValue = JOptionPane.showInputDialog("Enter length:");
}
}

Am I heading in the right direction?

	payRate = Double.parseDouble(inputValue);



	//calculate the gross pay

	grossPay = hoursWorked * payRate;

	fwt = grossPay * FWT_RATE;
	fica = grossPay * FICA_RATE;
	totalHoldings = fwt + fica;

	netPay = grossPay - totalHoldings;


	//display results

	JOptionPane.showMessageDialog(null, "Employee Name: " + name + "\nGross Pay:" + grossPay + "\nNet Pay: " + netPay);

	System.exit(0);

}
}

Re: Does anyone know Java?

If you're lost start slow and ignore the user for right now. Have you got the first part where the values are given to you (the yard's dimensions) working already? Once you do that you can easily change it so that it gets the values from the user.

Re: Does anyone know Java?

I'll post what I have later. I got pretty far, I have most of the calculations done. Suck at math so it was a pain trying to set them up in word form.
