How can I use a conditional TextField in JasperReports?

Question

I would like to have a pair of TextFields depending on a value. And the \"y\"-value should be adjusted depending on the empty space.

When the value is \"0\"

Answer 1

you can use like this

Declare RED as [class="java.lang.Number"]

while printing

$P{red}.intValue() == 0 ? null : $P{red}.intValue()

and enable Blank when null option of the field using

textField isBlankWhenNull="true">
