Is there a way to convert a float to a currency format

Question

Is there an object in Java that will format a float into some sort of currency format (string?)? Ideally if I have a float value of 3412.0 is there an easy way to get 3,412.00?
Thanks

Never tested this in production, but here's a start:
import java.text.*;
public class test
public static void main( String[] args )
String pattern = "\u00A4#,###.00";
DecimalFormat df = new DecimalFormat( pattern );
double[] nums = { 1f,
1.0f,
1.2f,
1.23f,
12f,
12.3f,
123.4f,
1234.5f,
1234.56f,
123456789,
123456789.9 };
for( int i = 0; i < nums.length; i++ ) {
System.out.println( nums[ i ] + " -> " + df.format( nums[ i ] ) );
output:
1.0 -> $1.00
1.0 -> $1.00
1.2000000476837158 -> $1.20
1.2300000190734863 -> $1.23
12.0 -> $12.00
12.300000190734863 -> $12.30
123.4000015258789 -> $123.40
1234.5 -> $1,234.50
1234.56005859375 -> $1,234.56
1.23456789E8 -> $123,456,789.00
1.234567899E8 -> $123,456,789.90
