Currently in the AWT, deprecated methods still contain<BR>
functional code internally.&nbsp; Newer methods which replace the&nbsp;<BR>
deprecated methods are calling the deprecated methods.&nbsp; As a result,&nbsp;<BR>
a derived class cannot disable deprecated methods by throwing an<BR>
exception or printing an error message.<BR>
&nbsp;<BR>
import java.awt.*;<BR>
public class MyList extends List {<BR>
&nbsp;&nbsp;&nbsp; // do not call this method!&nbsp; It is deprecated in
the base class<BR>
&nbsp;&nbsp;&nbsp; public synchronized void clear() {<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; throw new RuntimeException(&quot;java.awt.list#clear
is deprecated&quot;);<BR>
&nbsp;&nbsp;&nbsp; }<BR>
&nbsp;}<BR>
&nbsp;<BR>
The above example will not work, since List.removeAll() will call<BR>
List.clear(), which will now throw an exception!&nbsp; If you move the<BR>
functionality out of List.clear() and place it in the new method<BR>
called List.removeAll(), then I can successfully disable deprecated<BR>
methods in my derived class.<BR>
