Bom Dia
Pessoal alguem pode me ajudar recebo atraves de um socket um valor atraves do BufferedReader gostaria de atribuir esse valor a uma variavel "msg" para usar em outra classe porém aparentemente ele faz a atribuição normal mas na outra classe ele me retorna "null" segue codigos:
classe q recebe a variavel
import java.io.*;
import java.net.*;
public class Cliente{
String msg;
public String getmsg(){
return msg;
}
public void setmsg(String msg){
this.msg = msg;
}
public void go(){
while (true)
try{
Socket s = new Socket("127.0.0.1", 2805);
InputStreamReader streamReader = new InputStreamReader(s.getInputStream());
BufferedReader reader = new BufferedReader(streamReader);
msg = reader.readLine();
System.out.println(msg);
reader.close();
if (msg != null){ //Só para testar se estava atribuindo valor
new sysTray1();
} else {
System.out.println("Erro");
}
}
catch(IOException ex){
ex.printStackTrace();
}
}
public static void main (String[] args){
Cliente cliente = new Cliente();
//new sysTray1();
cliente.go();
}
}
Classe q gostaria de usar a variavel:
import java.awt.AWTException;
import java.awt.Image;
import java.awt.MenuItem;
import java.awt.PopupMenu;
import java.awt.SystemTray;
import java.awt.Toolkit;
import java.awt.TrayIcon;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
