Java how do I check if a Date is within a certain range

Question

I have a series of ranges with start dates and end dates  I want to check to see if a date is within that range   Date before   and Date after   seem to be a little awkward to use  What I really need is something like this pseudocode   boolean isWithinRange Date testDate        return testDate  gt   startDate  amp  amp  testDate  lt   endDate      Not sure if it s relevant  but the dates I m pulling from the database have timestamps

boolean isWithinRange Date testDate       return   testDate before startDate     testDate after endDate        Doesn t seem that awkward to me   Note that I wrote it that way instead of   return testDate after startDate   amp  amp  testDate before endDate     so it would work even if testDate was exactly equal to one of the end cases
