Revision as of 15:30, 29 February 2008
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).

Java
Console
<java>public class Beer{

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();//build and show the GUI }
