Thread: Basic client/server application

This is a basic client/server application that allow you to send command from server to client.
Code Server:

import java.io.*;
import java.net.*;
 
public class server {
	public static void main(String[] args) {
		ServerSocket ssok = null;
		Socket sok = null;
		PrintStream ps = null;
 
		int PORT = 1111;
 
		System.out.println("Opening Socket Server......");
		try {
			ssok = new ServerSocket(PORT);
		}catch(IOException e) {
			System.out.println("Error opening socket.");
		}
		System.out.println("Socket created......");
 
		try{
			System.out.println("Wait for connection.....");
			sok = ssok.accept();
		}catch(IOException e) {
			System.out.println("Connection error.");
		}
		System.out.println("Connection succesfull....");
 
		while(true) {
			try {
				BufferedOutputStream os = new BufferedOutputStream(sok.getOutputStream());
				ps = new PrintStream(os, true);
			}catch(IOException e){
				System.out.println("Errore");
			}
			System.out.println("Insert a command:");
			String command = reader.readString();
			if(command.equals("hello"))
				ps.println("hello");
			else if(command.equals("make"))
				ps.println("make");
			else
				System.out.println("Wrong command....");
		}
	}
}

Client code:

import java.io.*;
import java.net.*;
 
public class client {
	public static void main(String[] args) {
		Socket sok = null;
		BufferedReader is = null; //DataInputStream.readLine is deprecated, use BufferedReader instead
		int PORT = 1111;
 
		try{
			sok = new Socket("localhost", PORT);
			is = new BufferedReader(new InputStreamReader(sok.getInputStream()));
		}catch(IOException e) {
			System.out.println("Error opening socket.");
		}
		System.out.println("Socket created.....");
		try {
			String command;
			while((command = is.readLine()) != null) {
				if(command.equals("hello"))
					System.out.println("Hello World!!");
				else if(command.equals("make"))
					System.out.println("make me a cake!!!");
			}
		}catch(IOException e) {
			System.out.println("Reading Error");
		}
	}
}

reader is a class that help me to read inputstream.
Thank you for the attention.
