I'm trying to compile simple class, named Frame in package foo.bar:

package foo.bar;

public class Frame extends java.awt.Frame {
public static final long serialVersionUID = 1L;
public static void main(String [] args) {
System.out.println("HELLO: args = " + args);

As others have pointed out, the problem is that you import Frame. you
don't need to import something if you use the fully qualified name.
A side note, extending Frame is probably not what you really want to do.
It is unfortunate that so many examples and tutorials have you do this,
but in reality, you just need to compose a Frame with the various
Components you need. For the most part, the only time you need to
extend *any* Component or JComponent is when you are creating a custom
view of a specific type of data. And then you should only extend
JComponent or Canvas as I understand it.
This raises another question, OP: Why do you use 'java.awt.Frame' instead of 'javax.swing.JFrame'?
