DecimalFormat numform = new DecimalFormat("000,000.00");
System.out.println( "Num = " + numform.format(98765.432) );
Num = 098,765.43

When a number is negative, a minus sign is output in front of all the characters called for by the format pattern. If there are spaces on the left of the format pattern, they will be output, with the minus sign to the left of them. This is usually an error. See the last example.
What does the following fragment write?
DecimalFormat numform = new DecimalFormat("-0.00");
