Question 2: The following program is supposed to display a button in a frame, but the button doesn't display. What is the problem? How would you fix that? 1: import javax.swing.*; 2: 3: public class Test extends JFrame { 4: public Test () { 5: add( new JButton( "OK") ); 6: } 7: 8: public static void main ( String ] args ) { 9: JFrame frame = new JFrame(); %3D 10: frame.setSize( 100, 200 ); 11: frame.setVisible( true ); 12: } 13:}

I got another question. What would you do for this?
