NumberFormat vs double and long

S

StephaneLeFou

Hi,

I have a function which receives an amount (money) in fthe form of a
String. The values received can be of various formats such as:

"99,999.99"
"99 999.99"
"99 999 99"
"99999999"

and so on, depending on the user's input, because the input has not
been formatted yet with the Struts Validator for example...

However, the maximum valid number is: 99999.99d

I'm trying to figure out a way of checking if the passed String (once
parsed and so on) is no bigger than 99999.99d

So far I've been unsuccessful with the parse() and format() with
NumberFormat. Sometimes, it converts it to a double, sometimes to a
long...

Any help would be greatly appreciated.
Thanks.

A specification of the syntax and semantics of the
input language used for the numerals is required.
»Various formats such as ...« is not such a specification.

Oh, I meant: any unsigned number passed in a string that could fill a
mask like 9(9). The MaxLenght of the string is 9 characters and may
or may not include: commas, spaces and decimals.

Thanks again.

Assuming your string is in a variable called a:

//remove anything that isn't a number or a dot
a = a.replaceAll("[^0-9\\.]", "");

//Convert from String to a number variable
BigDecimal b = new BigDecimal(a);

if (b.compareTo(new BigDecimal("99999.99"))==1)
{
System.out.println("Number is bigger than 99999.99");

}

Works like a charm and couldn't be much more simpler than that.

Thank you very much, teacher :)
