99 bottles of beer
In this puzzle, print out the entire "99 bottles of beer on the wall" song. For those who do not know the song, the lyrics follow this form:
X bottles of beer on the wall X bottles of beer Take one down, pass it around X-1 bottles of beer on the wall X-1 bottles of beer on the wall ... Take one down, pass it around 0 bottles of beer on the wall
Where X and X-1 are replaced by numbers of course. Grammatical support for "1 bottle of beer" is optional. As with any puzzle, try to do it in as creative/concise/comical a way as possible (simple, obvious solutions allowed, too).

GUI
This version requires user interaction. The first two lines are shown in a text area on a window. The third line is shown on a button which you need to click to see the fourth line in a message box. The numbers update and the process repeats until "0 bottles of beer on the wall" is shown in a message box, when the program ends. <java>import java.awt.BorderLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JOptionPane; import javax.swing.JTextArea; public class Beer extends JFrame implements ActionListener{ private int x; private JButton take; private JTextArea text; public static void main(String[] args){ new Beer(); }
