What's this mean? - "uses or overrides a deprecated API."

Hi, I'm a newbie at Java and I'm getting this error when I try to compile my program:
"Note: C:\MarsLander\NewUser.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details."
I haven't a clue what is going on here, can anybody help?

Methods and classes may get deprecated with the threat that they will be removed form the API in a future version. Deprecated things can be but should not be used.
(Deprecated features can be undeprecated in a future version though. There are at least tow examples for this.)
As the message tells, compile it with the -deprecation flag and the compiler will report which method or class it is about.

Hi Mario,
With every latest Java version its APIs keep changing and some functions are removed or "deprecated", so if you are getting this error which means JRE you are using not have that function available so compile your code with Java -deprecation to suppress that error.
To check JRE version type Java - version on command prompt and then refer to Java API (also available online) to get detail about that particular function, otherwise you can also chose alternate function to achieve your programming objecting. I prefer if you see JCO API for help on this function.
Refer to sample code : http://www.sapdevelopment.co.uk/java/jco/jco_callfunc.htm

I believ this occured 2 years ago in playoffs. Maybe more. Forget, but the Leafs eliminated Flyers from POffs that year. The Flyers I also don't remember (the one knocked unconscious) but the one that was chasing him around was ... damn ... believe the last name began with an M, he is on the Rangers now... McArthy, thats right! Sandy Mcarthy.
As for Tucker. You are right. Every team needs a guy like him. Flyers have always had 1 or 2. Holding stick, flopping, and stuff. I really don't mind that, everybody does it... I even like Tucker from that point of view (though I hate watching my team fall victem to him :P).
If Quinn hates that style of play, why do the Leafs always rank in top 5 of penalties (the top this year) and among the top in fighting as well? If he wanted it stoppped it would stop. In fact he pushes for it, which you can see by the line match-ups he forces on ice. Also, he does complain a lot, but this is also a tactic. He complains to refs so they watch the other team more closely and will call penalties more on the other team. He does it well. (He is not the only one, Bowman used to do it, and Liniux (sp? does it for the Penquins...).

Show error overrides a deprecated API ?

what this error message.
Can I ignore this warning ?.
or how can i solve this warning?.Deprecation means a method or class has been identified as obsolete. That means that there is a newer and better alternative to something you are doing. It also means that perhaps one day the deprecated thing will disappear from the API (unlikely probably but could happen).
To solve the warning you will have to find out what it's complaining about.
javac -deprecation myJavaPgm.javaWill tell you what exactly is the problem.
Then you can look in the API for alternatives.

JRadioButton,ButtonGroup,overrides a deprecated API

Hi guys,
I need to know which JRadioButton is selected in a ButtonGroup. I have to methods to do it. The problem is that I need to communicate this to other class is in other file. I have enclosed a JRadioButton variable in the other class importing javax.swing.*. But I get this warning in that class when compiling.
Note: J:\MainObjectClass.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.
1)
public static JRadioButton getSelection(ButtonGroup group) {
for (Enumeration e=group.getElements(); e.hasMoreElements(); ) {
JRadioButton b = (JRadioButton)e.nextElement();
if (b.getModel() == group.getSelection()) {
return b;
return null;
On the other hand, I hava tried a different way, defining the second method. But I get the same warning in the main class now.
2)
public static String getSelection(ButtonGroup group) {
for (Enumeration e=group.getElements(); e.hasMoreElements(); ) {
JRadioButton b = (JRadioButton)e.nextElement();
if (b.getModel() == group.getSelection()) {
return b.getLabel();
return null;
Does somebody what I can do?????
Thanks in advance.

If you recompile with -deprecation you see which classes/methods are deprecated and you can use something else. You can also use the deprecated methods, but there's no compelling reason to do so.

The methods you used to instantiate your new dates has been deprecated and should no longer be used. This is just a warning though and your code will still work. Sun is just telling you that they no longer support those constructors for the Date class and that future releases of J2SE may not have them included in the API. If you wanted to, you could ignore it, or you could use the sample code instead for your Date creations:

I tried to register my stolen iPhone onto My Profile but it says that it's registered under another apple ID (which is not mine) What does this mean? Does it mean the person who stole my phone is using my phone under another Apple ID?!

Hi everyone,
My iphone and Ipad got stollen yesterday...
I registered my Ipad onto "my profile" but when I tried to register my Iphone 4 onto "My Profile" it says that the product has been registered under ANOTHER apple ID. What does this mean?! Does this mean that the thief is using my phone under a new apple ID?!
I am getitng abit paranoid because when I tried to download a new app onto my macbook pro, it says that someone had accessed my account from a new computer. I am so scared.. as I know that if they are able to access my apple ID account they can see my billing/card details. I tried to delete my billing address and card details on my apple ID account to prevent this from occuring but I can't. Please help
Many thanks,
Kim

You should change your AppleID password NOW. And if it says it was registered under another AppleID, the thief has probably done it.

Since pse 9 can only use up to camera raw 6.5 and the d600 needs at least 7.3 and the d800 needs at least 6.7, you can use the
8.6 adobe dng converter to convert those files to dng copies, which then pse 9 should open.
