Java loop to check for inputstream reader

Question

I have a server and client.java which can send and accept a message both ways via input and output stream but as soon as there is a connection a message is sent and then the server closes its self, so far I have put the buffered reader ect. in a finally block which is only activated when e == true (e for exit so I can stop it when I want) but it still stops the build after sending/receiving a message 1st question how can I stop it from closing its self? 2nd question how can I put input stream reader in a loop to continually test for input from client.java?

Client.java

package client;

import java.io.*;
import java.net.*;
import java.io.BufferedReader;

    // Variables declaration - do not modify                     
/**

public class Client extends javax.swing.JFrame {

;

    public Client() {
        initComponents();
    }
    private void jTextField1ActionPerformed(java.awt.event.ActionEvent evt) {                                            
    jTextField1.setText("");
    input = jTextField1.getText();
    send(input);     
    }                                           
    int port = 1234;
    String hostname = "localhost";
    String input,output;

    public void send(String text) {   
    try {
         Socket skt = new Socket(hostname, port);           /*Connects to server*/

         BufferedReader in = new BufferedReader(new
         InputStreamReader(skt.getInputStream()));          /*Reads from server*/
         System.out.println("Server:" + in.readLine());

         PrintWriter out = new PrintWriter(skt.getOutputStream(), true);
         out.println(text);                                   /*Writes to server*/
         out.close();    /*Closes all*/
         in.close();
         skt.close();

      }
      catch(Exception e) {
         System.out.print("Error Connecting to Server\n");
      } 
    }
    public void startUP() {

    }
    public static void main(String args[]) {
     Client c = new Client();
     c.startUP();
     c.send("Server is online");
      new Client().setVisible(true);

   }


    // Variables declaration - do not modify                     
    private javax.swing.JScrollPane jScrollPane1;
    private javax.swing.JTextArea jTextArea1;
    private javax.swing.JTextField jTextField1;
    // End of variables declaration                   
}

Server.java

package server;

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

class Server {
    /*
     To send string to client use "out.print(data)"
     To use info sent from client use "in.readLine()"
     */
        int port = 1234;
    String input,output;
    boolean e = false;
    String question = "how are you";
    String answer = "i am fine";

    public void send(String text) {
        ServerSocket srvr = null;
        Socket skt = null;
         PrintWriter out = null;
         BufferedReader in = null;
    try {
         srvr = new ServerSocket(port);
         skt = srvr.accept();                       /*Waiting for Connection from client*/
         System.out.println("Connection = true");

         out = new PrintWriter(skt.getOutputStream(), true);
         out.println(text);                                                  /*Write/Send to Client*/

         in = new BufferedReader(new
         InputStreamReader(skt.getInputStream()));                   /*Read from Client*/
         System.out.println("Client:" + in.readLine());
         input = in.readLine();

      } catch( Exception e) {
         System.out.println("Error Connecting\n");
      } finally {
        if(e == true){
        try {
         out.close();
         in.close();
         skt.close();               /*Closes all*/
         srvr.close();

         } catch (IOException e) {
        }
    }
    }
    }

public void testFor() {
    if(input.equals(question)){ send(answer); }
}

   public static void main(String args[]) {
       Server s = new Server();

       s.send("Client is online");  //sends a message to client
      // s.testFor();

   }
}

Answer 1

ok well to start of, to stop a while loop, at some point you have to say that statement is false or true (depending what u use in first place). so i.e if you say while(true). this will always be true as there is nothing to compare to therefore it will create infinite loop going on forever. however if you say we do something like that

 `while(x=true)'
  {
     x=false;
  }

this will ensure that you stop the while loop and you will not enter it again. How? well we enter the while loop under conditon that x is true. as soon as we enter that loop we declare x to be false. therefore on next iteration x will be false and as a result we will not enter while loop. Kinda straight forward isn't it ?
As of the problem it self, i suggest reading THIS article. It is very clear and nicely laid out and it will show you how to write good socket based program:)

Answer 2

1st question is to call the bufferreader, printwriter etc.. out of the methods then use the .close in a separate method which could be activated at any time.

for my 2nd question I found I can use a while loop:

    while(true) {
//code...
    }

Thanks for no one's help.
