Calendar .YEAR, .MONTH, DAY_OF_MONTH different than date.getDay() etc?

Question

I realized this:

Calendar c = new GregorianCalendar();
mYear=c.get(Calendar.YEAR);
mMonth=c.get(Calendar.MONTH);
mDay=c.get(Calendar.DAY_OF_MONTH);

And this:

Date d = c.getTime();
int day = d.getDay();
int month = d.getMonth();
int year= d.getYear();

Yield different numbers, is there some initialization I am missing? I care because I am using ORMLite and trying to store dates into a database, which is a Date object, but Date is being deprecated and so I am trying now to use Calendar but it doesn't seem that simple since the above code results in different answers for the day, month, and year.

Answer 1

the Date.getYear(), getMonth() and getDay() are deprecated and specifically ask you to use Calendar.get()

The reason why you are getting different answers is two-fold

getDay() returns the day of the week and not the date -- use getDate() here

getYear() returns year - 1900

Here is the relevant note from the API documentation

Deprecated. As of JDK version 1.1, replaced by Calendar.get(Calendar.YEAR) - 1900.
