Simple operation/expression in IReport

2004-03-24 08:12

Hi,

 

I need to perform a (hopefully) simple operation.

 

I have a field named "dueDate" which is a java.util.Date object. I have another field named "maxDelayDays" which is a java.lang.Integer object.

 

Now, I need a third field which is a sum of the two named "latestDueDate", and an instance of java.util.Date.

 

How do I do this in IReport?

 

Thanks

new Date((long)($F{dueDate}.getTime() + ($F{maxDelayDays).intValue() * 1000 * 60 * 60 * 24)))

Thanks Gregory.

 

Now, do I set this as part of the "Textfield expression" or the "Print when expression" of the field?

That depends on how you want to use it. If it is going to be displayed as another field in the detail, make it a variable and then refer to it in a textfield expression.
