COMPILING NOTE/ERROR

Question

I was wondering if anyone could shed some light on the note(s) that I receive when I trying to compile the following source code. Here are the note(s),as well as the source code! I am still fuzzy on how how to compile using deprecation to show the location of the deprecated API's.
Thanks!!!
Note: Summer.java uses or overrides a deprecated API
Note: Recompile with -deprecation for details
import java.util.*;
public class Summer
public static void main(String[] args)
// Date and time right now
Date start = new Date();
// Date and time on June 21st 2003
Date end = new Date(103,5,21);
// Number of milliseconds between today and June 21st
long interval = end.getTime() - start.getTime();
System.out.println("The current date and time is " + start);
System.out.println("The summer starts on " + end);
System.out.println("Number of ms in this period " + interval);

Answer 1

You can compile with -deprecation to show the details..
javac -deprecation Summer.java
In your case, it's a result of the following line..
Date end = new Date(103,5,21);
The constructor you are trying to use has been deprecated, so that's why you're getting the message. It's not an error, and your program will function, but you should consider using java.util.Calendar for Date calculations instead.
