Java Basic Learning Notes Java socket+swing design simple communication

In the original book "Java from Beginner to proficient (3rd edition)", the client can only send data once, I modified a little bit on this basis, and realized the one-way communication of sending data multiple times.

1. Server-side

Package Tcp_ip;import Java.io.bufferedreader;import Java.io.ioexception;import java.io.inputstreamreader;import Java.net.serversocket;import Java.net.socket;import Java.sql.date;import Java.sql.time;import Java.text.simpledateformat;import Java.util.simpletimezone;import Com.sun.org.apache.bcel.internal.generic.NEW; Import Javafx.beans.binding.when;import Io_test.bufferread;public class My_Server {private BufferedReader reader; Private ServerSocket ser_sock;private Socket socket;void my_server () {//TODO auto-generated constructor Stubtry {SER_SOC K = new ServerSocket (8766); System.out.println ("Waiting for Customer Connection"); Socket = ser_sock.accept (); reader = new BufferedReader (New InputStreamReader (Socket.getinputstream ())); while (reader! =null) {SimpleDateFormat forma = new SimpleDateFormat ("Yyyy-mm-dd hh:mm:ss"); SYSTEM.OUT.PRINTLN ("Connection succeeded:" +forma.format (New Java.util.Date ())); SYSTEM.OUT.PRINTLN ("Get Client Information for:" +reader.readline ());} Reader.close ();} catch (IOException e) {//TODO auto-generated catch blocke.printstAcktrace ();} }public static void Main (string[] args) {//TODO auto-generated method Stubmy_server sv = new My_Server (); Sv. My_Server ();}}

2. Client

Package Tcp_ip;import Java.awt.borderlayout;import Java.awt.container;import java.awt.event.actionevent;import Java.awt.event.actionlistener;import Java.io.ioexception;import Java.io.printwriter;import Java.net.Socket;import Java.net.unknownhostexception;import Javax.swing.jframe;import Javax.swing.jscrollpane;import Javax.swing.jtextarea;import Javax.swing.jtextfield;import Javax.swing.border.bevelborder;public class My_Client Extends Jframe{socket socket;private jtextarea ta = new JTextArea ();p rivate jtextfield tf = new JTextField ();p rivate Print Writer writer; Container c;public my_client (String titl) {//TODO auto-generated constructor Stubsuper (TITL); setdefaultcloseoperation (exit_on_close); c = Getcontentpane (); final JScrollPane Scollpane = new JScrollPane (); Scollpane.setborder (new BevelBorder (bevelborder.raised)); Getcontentpane (). Add (Scollpane, borderlayout.center); Scollpane.setviewportview (TA); C.add (TF, "South"); Ta.append ("Attempt to connect \ n"); try {socket = new socket ("127.0.0.1", 8766);} catCH (unknownhostexception E1) {//Todo auto-generated catch Blocke1.printstacktrace ();} catch (IOException E1) {//Todo Aut O-generated catch Blocke1.printstacktrace ();} Ta.append ("Connected, please enter send message \ n"); Tf.addactionlistener (new ActionListener () {public void actionperformed (ActionEvent e) {// TODO Auto-generated method Stubtry {writer = new PrintWriter (Socket.getoutputstream (), true); Writer.println (Tf.gettext ()); Ta.append (Tf.gettext () + "\ n"), Ta.setselectionend (Tf.gettext (). Length ()); Tf.settext ("");} catch (IOException E1) {//TODO auto-generated catch Blocke1.printstacktrace ();}});} public static void Main (string[] args) {//TODO auto-generated method Stubmy_client client = new My_client ("Connection Server"); . SetSize (+); client.setvisible (True);}}
