Question

I’m simply trying to send a message to another object but its not exactly changing unless I’m missing a important factor. I have one class to set the number and another class which gets, the class that gets is dependent on the correct number being set however although the set method returns 0 one the command line, the other object returns 1 when using the get method. This is the close class whihc holds both of the methods, each method is called from class A and Class B

public class Close {
    static int close =1;

    public synchronized void setClose(int x, Client)
    {
        /*
        while(turn !=0){
            try{
                wait();

            }
            catch(Exception e)
            {
                e.printStackTrace();
            }
        }*/
        close = x;
        System.out.println("set "+close);
    }

    public synchronized int getClose(ClientHandeler)
    {
        int x;
        /*
        while(turn==0){
            try{
                wait();
            }catch(Exception e)
            }
        }*/
        System.out.println("get "+close);
        x = close;
        return x;
    }

}

This is the handler class in which i wish to get the close integer from

import java.io.*;
import java.net.*;
import java.util.*;

public class ClientHandler implements Runnable {

private BufferedReader reader;
private Socket sock;//refering to socket class
//listens for the socket
private Server server; // call-back reference to transmit message to all clients
Client c = new Client();

public ClientHandler(Socket clientSocket, Server serv) {

    try {
            sock = clientSocket;
            server = serv;

            InputStreamReader isReader = new InputStreamReader(sock.getInputStream());
            reader = new BufferedReader(isReader);



     } catch (Exception ex) {
         ex.printStackTrace();
     }
}

public void run() {

    String message;




    try {

         int x = c.c.getClose(this);
         while(x!=0){
         x = c.c.getClose(this);//calls client and within client there is the close 
            System.out.println(x);

            Thread ct= Thread.currentThread();
            ct.sleep(3000);
            while ((message = reader.readLine()) != null) {

                System.out.println("read " + message);

                server.tellEveryone(message);
            }
        }       
    } catch (Exception ex) {
        ex.printStackTrace();
    }
}





}

Answer 1

Probably they both do not use the same Close object.

Close close = new Close();

Then make sure that both use the same close object!

If that is not possible, field close can be made static:

  public class Close {
static int close;
