Having problems linking two java classes getting a "deprecated API" error??

Question

Hi,
I am tryin to link one page to another in my program, however i get the followin msg:-
Project\alphaSound.java uses or overrides a deprecated API.
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

You 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,
