Help Please!!! Adding two Double values....

[chiragkini]

Hi Guys!

I am new to Jaspers IReport . I use this in netbeans 6.5 for reporting but I am facing one problem------>>>

I have two fields whose Expression class java.lang.Double, whose values are taken from database.

Now I want to add those two fields and display in Third Field, But whenever I use + operator to add those two fields in third field expression it gives me error " The operator +  is undefined for the argument type(s) java.lang.Double,  java.lang.Double"

I dont know why its not allowing to add two Double fields.. 

So please guys help me out with this problem....

Thanks in Advance...

you can solve this by using an expression like this "variable1.doubleValue()+variable2.doubleValue()"

Thanks Oxelad,

But when I tried to do this it gives me error saying "Cannot cast from double to Double"

 

so even if when i tried to convert values first into string the convert into double it fails.

For eg. when i do ($f{variable1}.toString()).doubleValue() +($f{variable2}.toString()).doubleValue() , it gives me error: "The method doubleValue() is undefined for type String....

 

Note: my variable values comes from database tables of type DOUBLE.

 

Hope u got it what is scenario...

It is a Java. Ok. The correct code should be like this one:

Double.valueOf($f{variable1}.doubleValue()+$f{variable2}.doubleValue())

Hey Thanks Oxelad, thanks a ton. Its working now, actually I was doing stupiity by using Double.valueOf($f{variable1}.doubleValue()) + Double.valueOf($f{variable2}.doubleValue()).

 

I got my mistake ...

Thanks once again :)

Oxelad.  Thanks a lot.  I am constantly struggling with Java in Jasper.  This helped me a lot.  I think this will save me lots of time in the future.

new Double( $f{variable1}.doubleValue()+$f{variable2}.doubleValue()) would work too
