Instructions: copy code sections and modify to your needs, decimalformat uses a string template to design your output.

//you first need to import the DecimalFormat class:
import java.text.DecimalFormat;
//then create a format object. this object can be used with doubles, as it uses a [i]decimal[/i]. It uses a template String to [b]teach[/b] Java how to ouput the objects.
//This example will be used as a standard format of money:
DecimalFormat money = new DecimalFormat("$0.00");
//Now that you have a money object. (declared either globally or locally) you can now [b]format[/b] your objects
//Note this example uses only 2 decimal places and a $, but any symbols or length is available.
//As an example of prniting a double value:
double amount = 4.333333333;
System.out.println(money.format(amount));
//what will be printed is: $4.33 as described by the template, this handles your percision and dollar sign with a single template!
