Comparing String problem?

[nitin403]

Hi all,

I need to compare a string which is double value with zero.

And do some conditional print of value.

I tried searching and using them.

But always failed in doing so.

It is like this.

There is a string.

and I want to check that if it is greater then 0 then print one thing or else print something else.

This string can be like 1234.12 also.

 

Thanks for your help in advance.

Hi,

Thanks for your reply.

 

Here is the case.

I have a field, let say

$F{UnusedCreditAmount} = "1234.12"

I need to display it in my report as red color when -ve and black when +ve

I know the code to print this field in Red.

 

I tried many combination but it always gives error message in IReport 2.0.5 while compling

Below is the error

Code:

he operator > is undefined for the argument 
type(s) Double, int   value = (java.lang.String)(((new
Double(((java.lang.String)field_UnusedCreditAmount.getValue()))>0) 

 

 

Thnaks for your help in advance

hi,

I found the solution.

I used following code

 

Code:

(Float.parseFloat($F{UnusedCreditAmount})) < Float.parseFloat("0"«») ? 
"<style forecolor='#ff0000'>" + $F{UnusedCreditAmount} + "</style>" : 
 $F{UnusedCreditAmount}
