IF statment: java.lang.Integer

[jenkins]

I have the following two fields/variables in my report:
$F{CostNeutral}: Field class: java.lang.Integer (0 or 1)
$V{persondays}: Field class: java.lang.Integer (calculates the difference between two dates)

I now want to enter a third field ($F{PD}: Field class: java.lang.Integer) with an if statement which should check the value in $F{CostNeutral} and then determine how to populate $F{PD}, i.e. with either "0" or "$V{persondays}". I have tried many variations of the following expression with no joy (still have to get up to speed on java!):

$F{CostNeutral}.equals( "1" ) ? "0" : "$V{persondays}"

Any help would be much appreciated!!

$F{CostNeutral}.equals( new Integer(1) ) ? new Integer(0) : $V{persondays}

works like a charm, cheers!
