Some people have asked about formatting decimal data in Java, since the 
default can be ugly. I don't want to spend time on it right now, but the process
isn't too bad.

<p>
First, you need to import an appropriate class:
<p>
import java.text.DecimalFormat;

<p>
Later, you need to create a variable of that class that demostrates the formatting that you want. E.g.
<p>
DecimalFormat twoDecPlacesFormat = new DecimalFormat ("0.00");
<p>
Once your program has executed that statement (and the variable is defined in the scope)
you can use it to specify the formatting for a decimal number. e.g.
<p>
System.out.println("Formatted variable: " + twoDecPlacesFormat.format(adoublevar) );
