Question

I need to get the first date of the current quarter as a java.util.Date object and the last date of the current quarter as a java.util.Date

You can use joda:

Date start = date.withMonthOfYear(((date.getMonthOfYear() / 3) + 1) * 3 - 2)
            .withDayOfMonth(1)
            .withTimeAtStartOfDay()
            .toDate();
Date end = date.withMonthOfYear(((date.getMonthOfYear() / 3) + 1) * 3)
            .withDayOfMonth(Month.of(((date.getMonthOfYear() / 3) + 1) * 3).maxLength())
            .withTimeAtStartOfDay()
            .toDate();

When DateTime date = new DateTime(2016, 8, 12, 1, 1, 1);

I get:

Fri Jul 01 00:00:00 CEST 2016
Fri Sep 30 00:00:00 CEST 2016
