Please avoid hurting Javas reputation by using outdated code. 1. Since Java 8 there are LocalDateTime/ZonedDateTime/etc. classes. They are immutable. LocalDateTime even works with Hibernate. 2. date.setDate(int date) is deprecated for nearly 20 years. The methods Javadoc clearly states that you are changing the object. The method even returns void. Don't use it. Why are you still using it? 3. If you still want to use the less comfortable Date and Calendar, they work fine if you use them as you are supposed to.
