printf formatting in Java

Here is my code:

System.out.printf("\n%-10s%9s%11s%13s%9s\n",
            "yearBuilt","area(sqf)","price","replaceRoof","sqfPrice");

System.out.printf("\n%-10d%9.1f$%11.2f%13s$%8.2f\n",
            house1.getYear(),house1.getSquareFeet(),house1.getPrice(),house1.isRoofChangeNeeded(),house1.calcPricePerSqf());

And here is the output I'm getting:

    yearBuilt area(sqf)      price  replaceRoof sqfPrice


    1996         2395.0$  195000.00         true$   81.42

This is the output I want:

    yearBuilt area(sqf)       price  replaceRoof sqfPrice


    1996         2395.0  $195000.00         true   $81.42

I tried using DecimalFormat but for some reason it didn't seem to work correctly when using it inside printf, when it worked normally in another area of my program. Any ideas on how to fix this?

It would be nice to be able to use the "$" sign with printf statements in java but we have to use the special class for that in java. The good news is that there are such available in the api.

Start with something like below.

DecimalFormat currencyFormatter = new DecimalFormat("$000000.00");
System.out.printf("\n%-10d%9.1f%11.2f%13s%8.2f\n",house1.getYear(),house1.getSquareFeet(),currencyFormatter.format(house1.getPrice()),house1.isRoofChangeNeeded(),currencyFormatter.format(house1.calcPricePerSqf());

Hope that helps.

The problem is that you specify the price to be 11 digits fixed before the decimal, and sqfPrice to be 8 digits which cause the padding spaces.

If you decorticate your print statement :

System.out.printf("$%11.2f", 195000.0f);//print $  195000,0
System.out.printf("$%8.2f", 81.42f);//print $   81,42

You might want to use NumberFormat instead 

NumberFormat currencyFormatter = NumberFormat.getCurrencyInstance(currentLocale);

Assuming you gave US locale, 

currencyFormatter.format(195000)

would output $195,000.00.
