Chat java. Naloko na c client.

mga boss. i'm practicing socket programming in java. chat ni cya
the problem is, di maka.connect ang client if unahon ug run ang server para mu.create ug socket.
mu.connect ra ang client if naka.run na cya daan, then paabot cya mu.run ang server para mucreate ug ServerSocket, dha pa cya mu.connect. LAINA UI! hahaha. bali man nuon. dapat mag.una ang server then musunod ug connect ang client.
here is the code of the client connection.
kung kbw mo, post mo mga bossing. then add ug mga comments. tnx

 try {
            
            boolean connected = false;
            do {
                try {
                    connection = new Socket( "127.0.0.1", 1234 );
                    connected = true;
                    
                    input_field.setEditable( true );
                    textArea.append( String.format( "Now connected to %s.\n", 
                    connection.getInetAddress() ) ); 
                } catch ( Exception e ) {
                    connected = false;
                }
            } while( !connected );
            
            
                    
            
            //read inputs
            Scanner in = new Scanner( new InputStreamReader( connection.getInputStream() ) );
            String line;
            while ( ( line = in.nextLine() ) != null ) {
                textArea.append( line + "\n" );
            }
            
        } catch ( IOException e ) {
            textArea.append( String.format( "%s\n", e.getMessage() ) );
        }

in my opinion mo work ra ni siya although naay mga flaws. I think the reason why dili siya maka connect sa imo server if mag una siya ug dagan is because maybe wla natarong ug close imo mga connections. Try to post your server code as well. Based ani na code lang I think naay nag exception but since imo ra gi mark as false imo connected variable nag infinite loop ka sa imo try catch block.

Here are my advice:

1. Try to display what went wrong. Put a stackTrace on your catch statement para maka balo ka unsay nahitabo ngano wla ka naka connect.
2. ALWAYS close your connections by using finally {} block. What ever happens sa imo code, make sure all connections are closed if wla na nimo gigamit.

i solved it na. nara koi g.tang2x. there is nothing wrong with the server. the problem was this.

 
 try {
            
            boolean connected = false;
            do {
                try {
                    connection = new Socket( "127.0.0.1", 1234 );
                    connected = true;
                    
                    input_field.setEditable( true );
                    textArea.append( String.format( "Now connected to %s.\n", 
                    connection.getInetAddress() ) ); 
                } catch ( Exception e ) {
                    connected = false;
                }
            } while( !connected );

maglabay cya ug NullPointerException. cguro wa pa niya nakita na.himo ang UI ana na part since ang pag.build sa ui ako man gbutang ug invokeLater na thread, so mag.una jud cya ug connect before mahimo ang UI. yeah dakpon unta cya sa exception but infinite cya
dakpon sa exception so not connected ghapun.
