IllegalArgumentExceptio - Date
Hi friends,
i need to set the date (2007,04,01 (yyyy,MM,dd)) to calendar class but it throws IllegalArgumentException
Calendar calEx1 = Calendar.getInstance();
calEx1.set(2007,04,01);
System.out.println("Set value : " + format.format(calEx1.getTime()));
Date dateObject =new Date();
dateObject = calEx1.getTime();
the below line are used in another class, i am just pass the dateObject (date object) to that class.
Date ex1 =new Date();
ex1 = dateObject;
Calendar fromServer = Calendar.getInstance();
// here i am trying to set the date from that class
fromServer.set(ex1.getYear(),ex1.getMonth(),ex1.getDate());
System.out.println(format.format(fromServer));
Thank you,

You give a Calendar object as parameter to the format method. You should provide a Date:System.out.println(format.format(fromServer));
should probably beSystem.out.println(format.format(fromServer.getTime()));
Note that as you have a Date object, you can use the Calendar.setTime(Date) method (you have probably noticed that the getYear, getMonth, etc. methods of Date are deprecated.)
Note that if you don't need to manipulate calendar fields, it is likely that you don't need a calendar (but I don't know what your actual code does.)

The getDate() method returns a java.util.Date object, not a day of the month.
fromServer.setTime(ex1.getDate());
It's an extremely important skill to learn to read the API and become familiar with the tools you will use to program Java. Java has an extensive set of [url=http://java.sun.com/javase/reference/api.jsp]online documentation[/url] that you can even [url=http://java.sun.com/javase/downloads/index.jsp]download[/url] for your convenience. These "javadocs" are indexed and categorized so you can quickly look up any class or method. Take the time to consult this resource whenever you have a question - you'll find they typically contain very detailed descriptions and possibly some code examples.

On a side note...
calEx1.set(2007,04,01);
I recommend using the Calendar constants for the month to avoid confusion with Java's 0-indexed month numbering. I also recommend not using octal literals (the numbers beginning with zero). Example:
calEx1.set(2007,Calendar.MAY,1);

Sorry, i tried u r code but it throws,
- JDK 1.6 - Compile -
DateDiff.java:63: setTime(java.util.Date) in java.util.Calendar cannot be applied to (int)
fromServer.setTime((int)ex1.getDate());
^
Note: DateDiff.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

I can't see what's wrong. A few comments, though.
Calendar's months are 0-based, so 04 gives you the 5th month, i.e., May. If you wanted April, use Calendar.APRIL.
I see no point in creating a new Date object in Date dateObject = new Date();. Just use Date dateObject;.
Date.getDate() does return the day of month (an int, not a Date object). It's deprecated, though. You may use simply
fromServer.setTime(ex1);
> Sorry, i tried u r code but it throws,[EDIT] Oh, my bad. I didn't see that ex1 was a Date object. Just use:fromServer.setTime(ex1);~

I am afraid ex1 is a Date in OP's code. And the deprecated Date.getDate() method actually returns an int (the day of the month represented by this Date object.)

I was confused. To clarify, the getDate() method of Calendar returns a Date object. Where is the IllegalArgumentException?

ok right, i made mistake.Thanks OleVV yawmark

Reply #1 doesn't say which line. If we assume that "format" points to a DateFormat object, the error is likely on the System.out.println() line, since format() takes a Date, not a Calendar. But the declaration of "format" isn't shown.
Where in reply #1 do you see the IllegalArgumentException?

It looked highly probable to me that format is a DateFormat.
I cannot find no other potential cause for an IllegalArgumentException to be thrown.
> But the declaration of "format" isn't shown.
Note that the fully qualified class names of Date and Calendar are not shown neither, everything is possible ;-P

Me neither, but I thought I'd ask the OP for clarification.
