IN JAVA

The code of a simple server is shown below. It offers the trivial service of accepting an integer value from a client and returning twice the value received. Explain the weakness in the design of the server and re-write it in light of your critique.

import java.util*;

import java.net*;

class DoubleServer{

private static int port = 1234;

public static main(String args[]){

try{

ServerSocket serversock = new ServerSocket(port);

while(true){

Socket socket = serversock.accept();

new Thread(new Double(socket)).start();

}

}catch(IOException e) {}

}

}

class Double implements Runnable{

Socket socket;

public Double(Socket s){socket = s;}

public void run(){

try{

DataInputStream in = new DataInputStream(socket.getIntputStream());

DataOutputStream out = new DataOutputStream(socket.getOutputStream());

int x = in.readInt();

out.write(2*x);

socket.close();

}

catch(IOException e) {}

}

}
