import trysource.trywindow;  import trysource.restraunts;  import java.awt.flowlayout;  import javax.swing.jframe;      public class trysomethingnew   {       public static void main (string[] args)      {        trywindow frame = new trywindow();          frame.settitle("try new");          frame.setsize(1000,900);          frame.setlayout(new flowlayout());          frame.setdefaultcloseoperation(jframe.exit_on_close);          frame.setlocationrelativeto(null);          frame.setvisible(true);     }  }

package trysource;    import trysource.trywindow.buttonclicked;  import java.awt.event.mouseevent;  import java.awt.event.mouselistener;  import javax.swing.jbutton;  import javax.swing.jframe;      public class trywindow extends jframe  {      jbutton jbtmexican = new jbutton("mexican");      jbutton jbtitalian = new jbutton("italian");                  public trywindow()      {          super("try new");                    add(jbtmexican);          add(jbtitalian);                  }//end trywindow constructor            class buttonclicked implements mouselistener      {                      @override          public void mouseclicked(mouseevent e)           {          }            @override          public void mousepressed(mouseevent e)           {                         }            @override          public void mousereleased(mouseevent e)           {          }            @override          public void mouseentered(mouseevent e)           {          }            @override          public void mouseexited(mouseevent e)           {          }                }              }//end class

package trysource;    public class restraunts   {      string restrauntname;      string restrauntaddress;      string restrauntphone;            public restraunts(string name, string address, string phone, int value)      {          restrauntname = name;          restrauntaddress = address;          restrauntphone = phone;        }//end constructor            restraunts joselocos = new restraunts("jose locos", "853 n glenstone ave, springfield, mo 65802",              "(417) 831-1300", 1);      restraunts amigos = new restraunts ("amigos mexican restaurant","2118 s campbell ave, springfield, mo 65807",              "(417) 887-1401", 2);      restraunts zios = new restraunts("zios italian kitchen", "1249 e kingsley st, springfield, mo 65804",              "(417) 889-1919", 3);      restraunts bambinos = new restraunts("bambinos cafe", "1141 e delmar st, springfield, mo 65807",              "(417) 862-9999", 4);                }//end restraunts

• add restraunts list
• group them (by type) using map
• use collections.shuffle randomise list , select first one

take at

• collections trail
• how use buttons, check boxes, , radio buttons
• how write action listeners

for more details

oh, , might gave @ how use cardlayout
