Amending simple program

[WillisTi]

I have this very simple program which calculates and displays the price of a product after sales tax has been added.

public class FindCost
{
  public static void main (String[] args )
{
  double price, tax;
  System.out.println("*** Product Price Check ***");
  System.out.print("Enter initial price: "); //prompt for input
  price = EasyIn.getDouble(); //input method called
  System.out.print("Enter tax rate: "); //prompt for input
  tax = EasyIn.getDouble(); //input method called
  price = price * (1 + tax/100);
  System.out.println("Cost after tax = " + price);
 }
}

I want to ammend the program so that:
- all currency values are displayed to two decimal places;
- line and tab spaces are used to improve the layout of the information displayed

Whats the best way to do this in the code?

Thanks

import java.text.*;

then make a DecimalFormat instance:

DecimalFormat twoDecimals=new DecimalFormat ("0.00");

then when you have a double value you write it like:

System.out.print(twoDecimals.format(theDoubleValue));

And for stating the obvious:

For newlines in a string, use '\n', for tabs use '\t';
