Deprecated API on a method.
I am getting a deprecated API warning when using the JTextField.getText() method. How do I find what method I should use instead? Is there a list somewhere with the replacements? Does someone know what to use instead of that method?
Yeah sorry guys I was using both a JTextField and a JPasswordField and I see now that you should use the method getPassword() for that. Sorry to bother everyone!!!

If you don't type "javac", you must be using an IDE.
In your IDE there should be some kind of configuration
tab or option for "compiler options" or compilation options
or compiler arguments... something like that.
put "-deprecation" in that text box and recompile.
Your compiler should tell you all about which methods
are deprecated -- you then go to your trust JavaDocs
and lookup those methods in the API and read WHY they
are deprecated (i.e. OLD, outdated, defunct, no longer used)
and what you should use instead. Then, correct your
code to no longer use the deprecated methods and instead
do things as suggested in the deprecation comments. -

If you wanted to, you could ignore it, or you could use the sample code instead for your Date creations:

Since I installed the last JDK update, I get the same warning:
MyFrame.show(): Deprecated API, show() in java.awt.Window has been deprecated.
But I try to find in Sun site, and at the method description it's not deprecated yet...
Any idea? What should I use instead of MyFrame.show()?Yeah, that is, I'm a little sleepy yet...
If you want to know, java.awt.Window.show() should be replaced by Component.setVisible(true). -

what this error message.
Can I ignore this warning ?.
or how can i solve this warning?.hi,

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. -
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. -
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.

Hello !
When I compile the following code it says
" CharacterCheck.java uses or overrides a deprecated API.
Recompile with -deprecation for details. "
What do I do ?
class CharacterCheck {
public static void main(String[] args) {
char ch = 'A' ;
boolean is_digit = false , is_space = false , is_other = false ;
if(Character.isDigit(ch))
is_digit = true ;
else
if (Character.isSpace(ch))
is_space = true ;
else
is_other = true ;
System.out.print("\n\tCharacter Check : " );
System.out.println(is_digit) ;
}God bless you .
NADEEM.to get details as to why you're getting the message,
compile your program with the -drprication option.
javac -deprication CharacterCheck.java
This will show you that what method call is being depricated.
In your example it's the Character.isSpace(ch) method call that is generating the depricated message. -
Force use of deprecated API to fail compilation
Ok, short question that I hope you can help me with. Is it possible to force the compilation to fail if I a deprecated API is used. Why? Well, we are a large number of developers and sometimes people use a method or class that has been deprecated because they are either lazy or can't find the new class/method.
This isn't possible with the default compiler. You would have to write a special compiler wrapper that calls the java compiler (sun.tools.javac.Main in tools.jar)
Can't you just hang a rubber chicken over the desk of the person who checked in bad code - that was what happened at my last job :)

hello friends,
A friends of mine gave me the code of his project. After running it in
NetBeans 4.0, I get the following message:
NewStudentEntry.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
Reason, that some of the methods have deprecated. How I could find these
deprecated methods?
thanks in advance
anandScreenThere must be a setting for compiler options somewhere in NetBeans.Indeed, there must. ;o)Hey, I don't use NetBeans. We have JBuilder, but it is way too slow (especially with the way our code works). 'vi' and command-line compilation/running on Unix is the way to go, anyway. I even just use jdb on the command line. It does the job.
When we first got Windows on our home computer, I hated it. I was used to the DOS commands for copying and renaming files. File Manager (and now Explorer)? Who needs it?! ;-) I'd rather type than use the mouse, any day. Always felt like I had more control, and knew more what I was doing, with the full DOS commands than with Windows File Manager. -

Oracle 10.2 Loadjava for SQLJ says "..uses or overrides deprecated API"
I just upgraded to 10.2 from 8.1.7 (platform is AIX 5L) and sqlj program was INVALID after upgrade.Running loadjava on the program seems successfull, and java class is VALID, but also get:
Note: MQBridge uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.
Well, after lots of reading to try and assess the significance of the error and identify the deprecated API, I think the sqlj script on UNIX will allow me to issue the 'deprecated' option to perhaps identify the old API. However, the I'm having trouble even getting the sqlj to work (I think it's in $OH/oc4j/bin with non-executable permissions) and the README in $OH/sqlj/demo seems incorrect.
The APIs in the program are:
import oracle.sqlj.runtime.Oracle
import java.sql.SQLException
import oracle.sql.CLOB
import com.ibm.mq.*
import java.math.BigDecimal
import java.util.*
import javax.swing.event.*
Perhaps someone versed in this arena can provide some guidance in what seems to be a straighforward problem (or maybe not a problem)? Sure would appreciate it!HI,
In my opinion, upgrading the RDBMS might not suffices.
I'd re-install SQLJ 10.2f rom the companion CD and check that its working fine in your environment using the following command:
$ sqlj -version
Oracle SQLJ Release 10.2.0.1.0 Production
Copyright (c) 1997, 2005, Oracle Corporation. All Rights Reserved.Oracle furnishes the following code samples under
$ORACLE_HOME/sqlj/demo/ to check your environment:
connect.properties // to be customized to your environment
TestInstallCreateTable.java
TestInstallJDBC.java
TestInstallSQLJ.sqlj
TestInstallSQLJChecker.sqlj
Then make sure that:
- the executables (script and binaries) are available under $ORACLE_HOME/bin.
- the PATH environment variable must include $ORACLE_HOME/bin.
- the CLASSPATH environment variable must include the following:
- the JDBC jars (ojdbc14.jar, or clases12.jar)
- ORACLE_HOME/sqlj/lib/translator.jar
- ORACLE_HOME/sqlj/lib/runtime12.jar
As described in chapter 10 of my book, here is how to use them to check
your environment:
// create a table for test purposes
$ javac TestInstallCreateTable.java
$ java -Doracle.net.tns_admin=$TNS_ADMIN TestInstallCreateTable
SALES table created
$
// Check JDBC install
$ javac TestInstallJDBC.java
$ java -Doracle.net.tns_admin=$TNS_ADMIN TestInstallJDBC
Hello JDBC!
$
// Check the SQLJ translator, runtime, and the application
$ sqlj TestInstallSQLJ.sqlj
$ java -Doracle.net.tns_admin=$TNS_ADMIN TestInstallSQLJ
Hello, SQLJ!
$Then check that SQLJ is installed in the database using
SQL> describe sys.sqljutlOtherwise, run the sqljutl.sql script to install it. In addition, the following query checks the availability of the SQLJ translator in the database (using system or a DBA account)
SQL> select object_type, status from all_objects where
2 dbms_java.longname(object_name) ='oracle/sqlj/checker/JdbcVersion';See chapter 10, 11 and 12 of my book for further coverage..

Note: Recompile with -deprecation for details.
Process completed.
this only happens when i add the bold piece of code to the class; even though the italic piece of code does take you to a new page?:-
public class alphaSound extends JPanel implements ActionListener
{static JFrame f = new JFrame("AlphaSound");
public alphaSound() {
public void actionPerformed(ActionEvent event) {
Object source = event.getSource();
else if(source == vowel)
{ Vowelm vm = new Vowelm();
vm.setSize(Toolkit.getDefaultToolkit().getScreenSize());
vm.show();
f.dispose();
else if(source == back)
{ MainPage main = new MainPage();
main.setSize(400,300);
main.show();
f.dispose();}
public static void main(String s[]) {
WindowListener l = new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
//JFrame f = new JFrame("AlphaSound");
f.addWindowListener(l);
f.getContentPane().add(new alphaSound());
f.setSize(Toolkit.getDefaultToolkit().getScreenSize());
f.show();
}here is the class its tryin to call
public class Vowelm extends JPanel implements ActionListener
{static JFrame v = new JFrame("VowelSound");
public Vowelm() {
..etc...
public static void main(String s[]) {
WindowListener l = new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
//JFrame f = new JFrame("VowelSound");
v.addWindowListener(l);
v.getContentPane().add(new VowelmSound());
v.setSize(Toolkit.getDefaultToolkit().getScreenSize());
v.show();
}Im pretty sure ther is some conflict between the two classes due to the way they are called and designed?
Hope you can help!
Kind Regards
RajYou may want to check your show() calls and see if
they can be replaced with setVisible(). Forexample,
in your Vowelm code, you have a static JFrame v.
At
the end of your main function, you use v.show().As
of JDK1.1, this has been deprecated in favour of
setVisible(boolean).hey show() in JFrame is from Window and in windowits
not deprecated ..
show is not decrecated thats for sure ... i dontknow
y you said that ...
you can look in docs as well..
True - but this in turn overrides show() from
java.awt.Component, which has been deprecated. My
guess is that's where the problem comes from.
Thanks for the Dukes!
FlicAnd then again - perhaps not. After looking into this a bit more, I take back my last comment about the Component override. However, as I said in my original reply, compiling with -deprecation should tell you which show() call is flagging the error. There is definitely one somewhere that the JVM doesn't like - without seeing your complete code, it's hard to say exactly where. Based on what you've posted, my guess is that it is within the Vowelm class.
Next time, I'll try to avoid 'shooting from the hip'.
Again, thanks for the Dukes,
Flic
