Sample question 8 from sun at the following URL
http://suned.sun.com/USA/certification/progsqwa.html


8.
1. import java.awt.*;
2.
3. public class Test extend Frame {
4. public Test() {
5. add( new Label("Hello") );
6. add( new TextField("Hello") );
7. add( new Button("Hello") );
8. pack();
9. show();
10. }
11. public static void main(String args[]) {
12. new Test();
13. }
14.}
What is the result?
A. The code will not complile.
B. A window will appear containing only a Button.
C. An IllegaArgumentException is thrown at line 6.
D. A window will appear but will not contain the Label, TextField, or Button.
E. A window will appear containing a Label at the top, a TextField below the Label, and a Button below the
TextField.
F. A window will appear containing a Label on the left, a TextField to the right of the Label, and a Button to the
right of the TextField .


Answer given is:
B.A window will appear containing only a Button.
Since on line 3, the keyword is "extend" instead of "extends",
program should not compile. Any thoughts???

It doesn't compile as written, for the very reason you cited.
