question 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.}
now the answers could be
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 .
there answer is B however i selected A bescause there is no extend keyword!
then on question 1
1. Given:
1.public class ArrayTest {
2. public static void main (String[] args) {i
3. Object[] ov;
4. String[] sa = { "Green", "Blue", "Red" };
5. ov = sa;
6. System.out.println("Color = " + ov[1];
7. }
8.}
What is the result?
A.fails to compile
B.prints Color=Blue
C.prints Color=Green
D.generates an exception at runtime
i choose A because it can not compile however sun says its B
I really hope the new test does not have errors like this.
