    Default 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
