How to add months to java.util.date field.

[acdacd]

Is there a way to add 2 months to a date field in iReport?

I created a variable with this expression: new java.util.Date($F{mydatefield}.add(Calendar.MONTH,2))

Compile error is “The method add(int, int) is undefined for the type Date”.

The variable and {mydatefield} are both java.util.Date.

Any suggestions? Thanks in advance.

Hi!

 

Method "add" is the method of java.util.Calendar, but not java.util.Date

 

You need:

1. Write java-class to work with dates (or find in internet, it's named approximately "DateUtils").

Example method of whis class:

public static Date addField(Date date, int field, int count) {

Calendar calendar = Calendar.getInstance();

calendar.setTime(date);

calendar.add(field, count);

return calendar.getTime();

}

 

 

2. Define classPath in iReport(Tools/Options/Classpath) with path to DateUtils.class

 

3. in iReport define Initial Value Expression for Variable:

ru.rtec.sgsr.util.report.DateUtils.addField($F{mydatefield}, Calendar.MONTH, 2)

 

With best regards
