Java Serialization:
Serialization
You could do it like this:
import java.net.*;
import java.io.*;
class testobject implements Serializable {
int value;
String id;
public testobject(int v, String s ){
this.value=v;
this.id=s;
}
}
public class SimpleServer {
public static void main(String args[]) {
int port = 2002;
try {
ServerSocket ss = new ServerSocket(port);
Socket s = ss.accept();
InputStream is = s.getInputStream();
ObjectInputStream ois = new ObjectInputStream(is);
testobject to = (testobject)ois.readObject();
if (to!=null){System.out.println(to.id);}
System.out.println((String)ois.readObject());
is.close();
s.close();
ss.close();
}catch(Exception e){System.out.println(e);}
}
}
import java.net.*;
import java.io.*;
public class SimpleClient {
public static void main(String args[]){
try{
Socket s = new Socket("localhost",2002);
OutputStream os = s.getOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(os);
testobject to = new testobject(1,"object from client");
oos.writeObject(to);
oos.writeObject(new String("another object from the client"));
oos.close();
os.close();
s.close();
}catch(Exception e){System.out.println(e);}
}
}
