Hello everyone, in this code I can search any word that I want in a text file using Socket , but the problem is... I need to read also the next column after I read the the word that I need to translate. I found I can do this with method readLine , but I'm not sure about this and I don't know how...
Server:
Java:
import java.net.ServerSocket;
import java.net.Socket;
 
public class Server {
 
    public static void main(String[] args) {
        System.out.println("Am pornit server...");
           try{
            ServerSocket ss=new ServerSocket(5000);
            for(;;){
             Socket cs=ss.accept();
             FirClient firPtClient=new FirClient(cs);
             firPtClient.start();
             System.out.println("Avem o conectare!");
            }//for;;
           }catch(Exception e){
               e.printStackTrace();
           }
 
 
    }
 
}

Java:
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.util.ArrayList;
 
//Clasa firului de execuție pentru tratarea clientului conectat la server:
class FirClient extends Thread
{
  private Socket cs;
  private BufferedReader bfr;
  private PrintWriter pw;
  ArrayList<String> al;//la creare firului incarcam datele
                                      // din fisier intr-un ArrayList
  public FirClient(Socket cs)
  {
   try{
      this.cs = cs;
      pw = new PrintWriter(cs.getOutputStream());
      InputStreamReader isr = 
                 new InputStreamReader(cs.getInputStream());
      bfr = new BufferedReader(isr);
      //incarcam fisierul cuvinte .txt in ArrayList:
      al=new ArrayList<String>();
      System.out.println("Se copiaza fisier in al");
      FileReader f=new FileReader("D:\\date.txt\\");
      BufferedReader bf=new BufferedReader(f);
      for(;;){
          String s=bf.readLine();
          if(s==null)break;//s-a terminat fisierul
          al.add(s);
      }
      bf.close();
      f.close();
    }catch(Exception e){
         e.printStackTrace();
         System.exit(1);}
  }
 
  public void run()
  {
   try{
       for(;;){
        String cuvant = bfr.readLine();
        if(cuvant == null)break;
        if(cuvant.equals(""))break;
        //cautare cuvant in ArrayList:
        boolean gasit=false;
        for(int i=0;i<al.size();i++){
            String crt=al.get(i);
            if(crt.equals(cuvant)){
               gasit=true;
               break;
            }
        }
        if(gasit)pw.println("da, este prezent si inseamna: ");
        else pw.println("nu, nu este prezent");
        pw.flush();
      }//for;;
     }catch(Exception e){e.printStackTrace();}
  }//run
}

Client:
Java:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.util.Scanner;
 
public class Client {
 
    public static void main(String[] args) {
        int N;
           Scanner sc=new Scanner(System.in);
           Socket cs=null;
           BufferedReader bfr=null;
           PrintWriter pw=null;
           try{
            cs=new Socket("localhost",5000)    ;
            InputStreamReader isr=
              new InputStreamReader(cs.getInputStream());
            bfr=new BufferedReader(isr);
            pw=new PrintWriter(cs.getOutputStream());
            System.out.println("S-a setat reteaua");
            for(;;){
              
               System.out.print("Cuvantul care trebuie tradus:");
               String cuvant=sc.nextLine();
               //daca este STOP : se va deconecta
               if(cuvant.equals("STOP")) {pw.println(""); pw.flush();break;}
               else  {pw.println(cuvant); pw.flush();}
               //Citim raspuns server:
               String textIn=bfr.readLine();
               if(textIn==null)break;
               System.out.println(textIn);
            }//for;;
           }catch( IOException e){
               e.printStackTrace();
           }
           System.out.println("Client m-am deconectat !");
    }//main
}
I put also the text file to help more if I didn't explain corectly.
