Little help for the beginer

Question

when I try to compile this program
import java.applet.Applet;
import java.awt.*;
public class OnnurTilraun extends Applet
     TextField t1, t2;
     Button b1;
     Label a1;
     public void init()
          t1 = new TextField(20);
          t2 = new TextField(20);
          b1 = new Button("Heilsa");
          a1 = new Label("Nafn:");
          this.add(a1);
          this.add(t1);
          this.add(b1);
          this.add(t2);
     public boolean action(Event e, Object o)
          if (e.target == b1)
               t2.setText("Good day" + t1.getText());
               return true;
          return false;
I get this message(Note: "Filename".java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.
Tool completed successfully)
but when I try to run the applet the appletviewer can�t start the applet so I recompile with -deprecation I get this message("filename".java:26: warning: action(java.awt.Event,java.lang.Object) in java.awt.Component has been deprecated
     public boolean action(Event e, Object o)
^
1 warning
Tool completed successfully)
What to do, I don�t know so I asking you

Answer 1

The warning message you get about deprecation is a warning and not a fatal error, and you may ignore it. It means that you use code that is considered "outdated", and that may (or may not) be discontinued in some future JVM. It is probably not the reason you can't run the applet. The reason appletviewer won't start the applet is hard to know without knowing what error message you get, but a wild guess is that there is some minor error in html file you use to start the applet
If you don't want to ignore the deprecation warning, do the rewrite virum suggested. As for the problem with "cannot resolve symbol", you need to import the ActionEvent class. Add
import java.awt.event.*;together with your other import statements.
