Passing Java objects (Object serialization) through socket)

This article mainly implements J: Passing Java objects through socket. The method used is object serialization. The method is to establish a C/S connection through socket, and read and write objects through objectoutputstream and objectoutputstream. The only thing to note is that the passed Java object must implement the serializable flag interface. The Code includes: Java object class, employee, Socket Client class, and server class. The main code is as follows:

Java object class:

Import java. Io .*;
Import java. util .*;

Public class employee implements serializable {

Private int employeenumber;
Private string employeename;

Employee (INT num, string name ){
Employeenumber = num;
Employeename = Name;
}

Public int getemployeenumber (){
Return employeenumber;
}

Public void setemployeenumber (INT num ){
Employeenumber = num;
}

Public String getemployeename (){
Return employeename;
}

Public void setemployeename (string name ){
Employeename = Name;
}
}

Client class:

import java.io.*;import java.net.*;public class Client {   public static void main(String[] arg) {      try {         Employee joe = new Employee(150, "Joe");         System.out.println("employeeNumber= "                            + joe .getEmployeeNumber());         System.out.println("employeeName= "                            + joe .getEmployeeName());         Socket socketConnection = new Socket("127.0.0.1", 11111);         ObjectOutputStream clientOutputStream = new            ObjectOutputStream(socketConnection.getOutputStream());         ObjectInputStream clientInputStream = new             ObjectInputStream(socketConnection.getInputStream());         clientOutputStream.writeObject(joe);         joe= (Employee)clientInputStream.readObject();         System.out.println("employeeNumber= "                            + joe .getEmployeeNumber());         System.out.println("employeeName= "                            + joe .getEmployeeName());         clientOutputStream.close();         clientInputStream.close();      } catch (Exception e) {System.out.println(e); }   }}

Server class:

Import java. Io .*;
Import java.net .*;

Public class server {

Public static void main (string [] Arg ){

Employee Employee = NULL;

Try {

Serversocket socketconnection = new serversocket (11111 );

System. Out. println ("server waiting ");

Socket pipe = socketconnection. Accept ();

Objectinputstream serverinputstream = new
Objectinputstream (pipe. getinputstream ());

Objectoutputstream serveroutputstream = new
Objectoutputstream (pipe. getoutputstream ());

Employee = (employee) serverinputstream. readobject ();

Employee. setemployeenumber (256 );
Employee. setemployeename ("John ");

Serveroutputstream. writeobject (employee );

Serverinputstream. Close ();
Serveroutputstream. Close ();

} Catch (exception e) {system. Out. println (E );
}
}

}
