-Xlint:deprecation

I have the following code:
(BTW: theButton is a two-dimensional array of JButton objects)
theButton[0][0].enable(false);I've also tried:
theButton[0][0].disable();They both give me the same error:
Note: C:\.....\tttGUI.java uses or overrides a deprecated API.
Note: Recompile with -XLint:deprecation for details.Can anyone please help me with this???
This is a program that I'm doing as a small project for school, for a bit of extra credit. Thanks in advance!

This is a warning rather than an error - that is, your code will compile and run. But you are advised to change your code because what you have written is problematic in some way (won't be supported in the future etc).
The idea is that you do exactly what the message says, you recompile:javac -cp . -XLint:deprecation *.javaor whatever command it is that you compile with. The important bit is the "-XLint:deprecation" part. The compiler will tell you exactly what is wrong and is generally very good about telling you how to fix it.
(The fact that you have identified the disable() method as the culprit suggests that you have done this? Also I don't think enable(false) will give you the deprecation warning - it just won't compile.)
There is another way to see what you should do instead of disable() - read the API documentation. Again, it is very good at explaining what you should do when a particular method is deprecated. The API for JButton is here: http://java.sun.com/javase/6/docs/api/javax/swing/JButton.html

Recompile with -Xlint:deprecation, whaat is it?

Hi, all!
When I'm compiling a prgm, I get this note: Recompile with Xlint:deprecation for details.
buttons.java uses or overrides a deprecated API.
I don't know what is it, and what does it prompt me to do.
Your help is highly appreciated.

An API you are using has been deprecated ^1^ (should no longer be used, for example Thread.stop ^2^ has been depricated as it is not safe to use).
Compiling with "Xlint:deprecation" will tell you what you are using, you can then look that up in the API to tell you what you need to do instead.

Note: recompile with -Xlint :deprecation for detailsThis is a warning that means that a class or method that you are using in your code is deprecated. A class or a method can be deprecated for several reasons:
e.g. the class/method could contain an error which makes the code unstable, the class/method could be written in a non standard way, the class/method could have been replaced by a more efficient/better/improved class/method
The deprecation message is only a warning. The code will compile even when deprecated. However, most code is deprecated for a reason, so you should try to find out what the substitution is (if one exists).
To find out what the problem is, the java compiler suggests you recompile using -Xlint: deprecation.
So instead of compiling using
javac YourClass.java
type
javac YourClass.java -Xlint:deprecation
You should get a message such as:
C:\Jenjava\Test\PacMan.java:56: warning: [deprecation] isFocusTraversable() in java.awt.Component has been deprecated
public boolean isFocusTraversable(){
Look up the offending method in the API at http://java.sun.com/j2se/1.5.0/docs/api/
It says:
isFocusTraversable
@Deprecated
public boolean isFocusTraversable()Deprecated. As of 1.4, replaced by isFocusable().
So, to get rid of the warning (and use the current method) we replace the isFocusTraversable() with isFocusable().
Make sense?

container.getParameter() returns Object, not String.

@SuppressWarnings("deprecation") is not working as described in the Tutoria

@SuppressWarnings("deprecation") is not suppressing warnings when I compile the below code on SDK 1.6.0. This code is copied straight from the Java Tutorial page at http://java.sun.com/docs/books/tutorial/java/javaOO/QandE/annotations-answers.html
Any hints would be appreciated.
Thank you,

public class MyHouse implements House {
    @SuppressWarnings("deprecation")
    public void open() {}
    public void openFrontDoor() {}
    public void openBackDoor() {}
}I get the message
"MyHouse.java uses or overrides a deprecated API."
I copied both the interface and the code from the tutorial page. The message does appear if I replace
@SuppressWarnings("deprecation") with
@Deprecated.
The interfac is
public interface House {
     * @deprecated use of open is discouraged, use
     * openFrontDoor or openBackDoor instead.
    @Deprecated
    public void open();
    public void openFrontDoor();
    public void openBackDoor();
}

You have, as far as I can tell, found a bug in Sun's compiler.
Java language Specification 3rd edition, p#9.6.1.6, says:
9.6.1.6 Deprecated
A program element annotated @Deprecated is one that programmers are discouraged from using, typically because it is dangerous, or because a better alternative exists. A Java compiler must produce a warning when a deprecated type, method, field, or constructor is used (overridden, invoked, or referenced by name) unless:
The use is within an entity that itself is is annotated with the annotation @Deprecated; or
The declaration and use are both within the same outermost class; or
The use site is within an entity that is annotated to suppress the warning with the annotation @SuppressWarnings("deprecation")
Use of the annotation @Deprecated on a local variable declaration or on a parameter declaration has no effect.
Using Java 6, I verified that the following code issues a warning when compiled:
interface House {
     * @deprecated use of open is discouraged, use
     * openFrontDoor or openBackDoor instead.
    @Deprecated
    public void open();
    public void openFrontDoor();
    public void openBackDoor();
class MyHouse implements House {
    @SuppressWarnings("deprecation")
    public void open() {}
    public void openFrontDoor() {}
    public void openBackDoor() {}
}The compiler produced these results:
Note: Xy.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.This bug (resolved in Mustang) may be involved.

Suppress deprecated warning?

My code is extending an abstract class. In the abstract class they have added a @deprecated tag above the no arg constructor. In my class I'm not defining a no arg constructor and I'm getting the warmingwarning: [deprecation] AbstractAuthenticationToken() in
org.acegisecurity.providers.AbstractAuthenticationToken
has been deprecated I've added -Xlint:-deprecation to my ant javac; no dice. I also added the @SuppressWarnings("deprecation") and declared my own no arg constructor and that didn't help either.
I'm using 1.5.0_06-b05.
Help! I hate warnings I can't do anything about and that aren't my fault!

ctor is short for "constructor".
You can't override constructors, anyway.
You probably have this:
public class MyClass extends ClassWithDeprecatedConstructor
    public MyClass(String text)
       System.out.println(text);
}That code implicitly calls "super()" as the first line of MyClass. But, that constructor is deprecated. You want this:
public class MyClass extends ClassWithDeprecatedConstructor
    public MyClass(String text)
       super(text, 5); // EXPLICITLY call a super constructor.
       System.out.println(text);
}Where ClassWithDeprecatedConstructor takes a String and an int:
public ClassWithDeprecatedConstructor(String text, int num)
}

How to find deprecated code

Hi there
I've just been handed over a great big project that was coded a couple of years ago and have just recompiled most of it - problem is that the compiler keeps telling me that the code has deprecated stuff in it but it won't tell me WHERE! (I'm using netbeans 4.1, Java 5.0)
Does anyone know of a tool that can pick out deprecated code or wether netbeans can do this please?
Cheers
JJ

How to configure in build the option "Xlint:deprication"

Hi all,
how I can define the "Xlint:deprication" option in Eclipse?
I would follow the warning:
     [javac] WARNING: Note: Some input files use or override a deprecated API.
     [javac] WARNING: Note: Recompile with -Xlint:deprecation for details.
     [javac] WARNING: Note: Some input files use unchecked or unsafe operations.
     [javac] WARNING: Note: Recompile with -Xlint:unchecked for details.
But I don't know, how to do this.
Can you help?
Thanks
Sven

Hi Sven,
Have you checked your settings under <em>Java u2192 Compiler u2192 Errors/Warnings</em> section <em>Deprecated and restricted API</em> (either project settings if defined there or the general settings)? As long as I don't have configure to give error messages for deprecated features I can still use them and the compiler doesn't complain (or spits out just a warning depending on what I set).
Cheers, harald

Login page and -Xlint message on compilation

WHAT DOES IT MEAN TO RECOMPILE WITH -Xlint?
Any idea what this is about and how to circumvent it?

that's means that you've used a deprecated method in your java code.
recompile your code as the following:
javac -Xlint MyClass.java

hi,

Note: Recompile with -Xlint:deprecation for details.
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.
