Image via WikipediaDo not use the method for in your frequently used methods.
instead of creating new instances use
Calendar.setTime(DATE)
otherwise each instance use lots of memory: 432 Bytes
DO NOT USE LIKE THIS
while(condition){
Calendar calendar = Calendar.getInstance();
calendar.setTime(someDate)
int month = calendar.get(Calendar.MONTH);
}
USE LIKE THIS
Calendar calendar = Calendar.getInstance();
while(condition){
calendar.setTime(someDate)
int month = calendar.get(Calendar.MONTH);
}
I found it very interesting that these two methods are not working same 
SELECT add_months(TO_DATE(’28-FEB-2007′), 1) FROM dual = 31-MAR-2007
while
java.util.Calendar c=..//28-FEB-2007
c.add(Calendar.MONTH,1); // gives 28-MAR-2007
which one is true ?
for the situation I am dealing java calculation is correct !
java vs Oracle and again winner is java !!!!
