Today I had to compare to dates to find out, if the are on the same date. Both dates had a DateTime format. So my first thought was to just strip the date part. I looked at the java.util.Date class and found that most of the methods are deprecated.
Sure, you can pass the java.util.Date objects to a java.util.Calendar and sethours, minutes and seconds to zero.
But I was looking for a smarter way to accomplish the goal. Joda-Time provides a quality replacement for the Java date and time classes. Joda-Time has been created to radically change date and time handling in Java. The JDK classes Date and Calendar are very badly designed, have had numerous bugs and have odd performance effects.
Using Joda, comparison of dates is easy as pie. The toDateMidnight() method for example sets the time part to zero.
Now you can do the compare with a simple date1.compareTo(date2) .
