swing - Java Menubar Action to a Class -

i have java menubar in program has 1 option 2 sub-options, e.g. file -> save, close. instead of save , close, options server , client. action event 1st option have java action listener:

public class serveraction extends abstractaction     {         public serveraction()         {             super();         }         public void actionperformed(actionevent e)         {             joptionpane.showmessagedialog(null, "test");         }      } 

so works when click on file->server, pops window says test. have server class (that have tested separately , know works) looks this:

public class socketserver {      public static void main(string[] args) throws exception {         ...     }        private static class clientlistenthread extends thread {                 public clientlistenthread(socket socket, int clientnumber){             ...         }                public void run() {             ...         }     }      private static class serversendthread extends thread {               public serversendthread(socket socket) {             ...         }                public void run() {             ...         }     } } 

now need call socketserver class when click on server option of main program can start server code , wait , listen client connections. question is, how start entire socketserver class code serveraction class?

your nested-classes private means visible in serversocket class. can provide helper method more visibility or change class declaration signature more visibility.

example helper method:

public class socketserver { . .  //nested classes declaration      public static void startserver(){    //code start threads new somethread().start();  }     } 

and in action

public class serveraction extends abstractaction{         @override         public void actionperformed(actionevent e){             socketserver.startserver();             joptionpane.showmessagedialog(null, "test");          } } 

it great if can notify when client connected , on, i'd recommend take swingworker provide helpful tool handle notification between background thread , gui thread.

note : great if implements runnable rather extend thread, not adding special functionality thread there no reason, more details here --> "implements runnable" vs. "extends thread".
