Question about the date API usage

[Julien Martin]

Hello,
What I want to achieve is quite simple to describe, i.e. I want to return the current date (as a java.util.Date) out of which I will have substracted 30 days.
For example today's date is the 20th December 2007, I want to get the following date: 20th December 2007 - 30 days that is the 20th of November.
Any clue?
Thanks in advance,
Julien.

Found the solution:

private Date centralizationMonth;
   
public MyConstructor() {
GregorianCalendar gc = new GregorianCalendar();
gc.add(Calendar.DAY_OF_MONTH, -30);
this.centralizationMonth = gc.getTime();
}
