4–Laboratoriya ishi: Telekommunikatsiya klient-server nazariyasi asosida aloqa tizimlari dasturlarini loyihalash va yaratish

Ishdan maqsad: Telekommunikatsiya klient-server nazariyasi va qo‘llanilish sharoitlari bilan tanishish. Aloqa tizimlarida klient va server qismlarining asosiy farqlari va vazifalarini o‘rganish.

Ishni bajarish tartibi:

Kodni kiritamiz client bilan serverni yaratamiz

Kiritilgan kodni korinishi

package lab4tds;

import java.io.*;

import java.net.*;

class server

{

public static void main(String argv[]) throws Exception

{

String qandaydirMatn;

String qayta_Ishlangan_Matn;

ServerSocket welcomeSocket = new ServerSocket(6789);

System.out.println("Server ishga tushdi!");

System.out.println("Kliyentdan so'rovni kutmoqda...");

while(true)

{

Socket connectionSocket = welcomeSocket.accept(); //so'rovni kutish

System.out.println("Kliyent server bilan bog'landi");

BufferedReader inFromClient = new BufferedReader(new InputStreamReader(connectionSocket.getInputStream()));

DataOutputStream outToClient = new DataOutputStream(connectionSocket.getOutputStream());

qandaydirMatn = inFromClient.readLine();

System.out.println("Server kliyentdan so'rovni qabul qildi");

System.out.println("Kliyentdan qabul qilingan matn: "+qandaydirMatn);

qayta_Ishlangan_Matn = qandaydirMatn.toUpperCase() + '\n';

outToClient.writeBytes(qayta_Ishlangan_Matn);

System.out.println("Server qabul qilingan so'rovni qayta ishlab kliyentga jo'natdi");

System.out.println("Qayta ishlangan matn: " +qayta_Ishlangan_Matn);

}

}

}

class client {

public static void main(String argv[]) throws Exception

{

String qandaydirMatn;

String qayta_Ishlangan_Matn;

BufferedReader inFromUser = new BufferedReader(new InputStreamReader(System.in));

System.out.println("Kliyent ishga tushdi!!!");

Socket clientSocket = new Socket("localhost", 6789);

System.out.println("Kliyent server bilan bog'landi");

DataOutputStream outToServer = new DataOutputStream(clientSocket.getOutputStream());

BufferedReader inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));

System.out.println("Serverga jo'natsh uchun ixtiyoriy matnni kiriting:");

qandaydirMatn = inFromUser.readLine();

outToServer.writeBytes(qandaydirMatn + '\n');

System.out.println("Kiritilgan matn serverga jo'natildi");

qayta_Ishlangan_Matn = inFromServer.readLine();

System.out.println("Qayta ishlangan matn serverdan keldi: " + qayta_Ishlangan_Matn);

clientSocket.close();

//System.out.println("Kliyent soketi yopildi!");

}

}
