Thread: DecimalFormat error when compiled

I am new to Java, and having problems with the use of DecimalFormat. When I compile the program it gives me an error so it doesn't work. I am not sure what I am doing wrong. I think that I am using the syntax correctly. When I take out the DecimalFormat it compiles and runs, but I would like the output with commas. What am I doing wrong here?

import javax.swing.JOptionPane;
import java.text.DecimalFormat;
public class yeargas
{
	public static void main(String[] args)
	{
		int tank, month;
		double year, yearx ,total;
		String input;
		DecimalFormat formatter=new DecimalFormat(0,000);
		//get the average cost to fill 1 tank of gas
		input=JOptionPane.showInputDialog("What is the average cost to fill 1 tank of gas? ");
		tank=Integer.parseInt(input);
		//get the x number of times you fill in a month
		input=JOptionPane.showInputDialog("What is the average number of times you fill your car in a month? ");
		month=Integer.parseInt(input);
		//calculate the cost for a month
		//multiply that by 1 year
		year=(tank*month)*12;
		//get the x number of years to calculate
		input=JOptionPane.showInputDialog("How many years do you want to calculate for? ");
		yearx=Integer.parseInt(input);
		total=yearx*year;
		//display the aproximate total cost for x
		JOptionPane.showMessageDialog(null,"Your average cost of gas for "+yearx+" is $"+(formatter.format(total))+".");//total+".");
		System.exit(0);
	}
}

Thanks for help. I didn't catch it. I am in a room that is about 93 degrees with a fan as my only saving grace.

How do I do that, so that I can do it the next time around.
