Thread: How to add commas to bigger numbers?

Okay so I would like to get commas in my output for bigger numbers like 1,000.00 10,000.00 etc...This is my program. Everything compiles just fine and I get the right output but again would like commas.

import java.text.DecimalFormat;
import java.util.Scanner;
import java.io.*;
 
public class propertyTax
{
	public static void main(String[] args) throws IOException
	{
		String fileName;
		double assessedValue;
		double taxableAmount;
		double taxRate;
		double propTax;
		String newDecimal1;
		String newDecimal2;
		String newDecimal3;
 
		Scanner keyboard = new Scanner(System.in);
 
		System.out.println("What is the Assessed Value of your property? ");
		assessedValue = keyboard.nextDouble();
 
		taxableAmount = (0.92 * assessedValue);
		taxRate = (0.0105 * taxableAmount);
		propTax = taxRate;
 
		DecimalFormat formatter = new DecimalFormat("#0.00");
		newDecimal1 = (formatter.format(assessedValue));
		newDecimal2 = (formatter.format(taxableAmount));
		newDecimal3 = (formatter.format(propTax));
 
		PrintWriter outputFile = new PrintWriter(new FileWriter("Tax.txt"));
 
		outputFile.println("Assessed Value:			$" + newDecimal1 + "\n"
				        +"Taxable Amount:			$" + newDecimal2 + "\n"
				        +"Tax Rate for each $100.00 	$1.05\n"
				        +"Property Tax: 	   		$" + newDecimal3 + ".");
 
		outputFile.close();
	}
 
}

--- Update ---

These are some of the values that are in/outputted

Assessed Value: 100000.00
Taxable Amount: 92000.00

Did you try reading the DecimalFormat API page?
