@Deprecated: Pls comment

Question

When I add the @Deprecated annotation to the method f() and try to invoke it, the compiler doesnt generate any warning/error. Can u pls let me know why.
Java Build: 1.5.0_06-b05
Thank You.
import java.util.*;
public class PreDefEnumTest
     @Override
     public String toString()
          return "Test Override";
     @Deprecated public void f()
     @SuppressWarnings("unchecked")
     public void g()
          List<Integer> l=new ArrayList<Integer>();
          List li=l;
          li.add(new Object());
     public static void main(String args[])
          PreDefEnumTest t=new PreDefEnumTest();
          t.f();
}

The fact that something is deprecated means that it is not for other users to invoke. However, it may be that it is entirely appropriate for your own code to invoke it.
In which case, the deprecation acts to discourage external use until such time as you can safely change the API to reduce the access to the method, not remove the method.
E.g. before:
// Leaks private info!
@Deprecated
public int getState() {
public void useState() {
   useState(getState());
// ...After:
private int getState() {
public void useState() {
   useState(getState());
// ...
