如何从日期字符串中扣除一日

Question

I have an SQL Parameter Enddatum , it is a String. If I create a Textfield with the expression like:

new java.text.SimpleDateFormat("yyyy-MM-dd").parse( $P{Enddatum})

This works.

But I want to subtract one day from Enddatum . Like:

new java.text.SimpleDateFormat("yyyy-MM-dd").parse( $P{Enddatum}) - 1 DAY

But it doesn't work.

What can I do?

尝试这个

new java.text.SimpleDateFormat("yyyy-MM-dd").parse( $P{Enddatum}) - 1
