通过在java中的ArrayList TCP？ [英] Arraylist through tcp in java?

问题描述

我如何在Java中通过TCP发送一个ArrayList？
我需要发送的整数的ArrayList，从客户端到服务器，反之亦然。

解决方案

 进口java.io. *;
进口java.net *。
进口的java.util。*;
导入的java.util.concurrent *。公共类SerializeOverSocket {    私有静态ExecutorService的ExecutorService的=
                    Executors.newSingleThreadExecutor（）;    公共静态无效的主要（字串[] args）抛出异常{
        //启动服务器监听客户端
        executorService.submit（新服务器（））;
        视频下载（100）;
        //从客户端发送一个ArrayList
        ArrayList的＆LT;整数GT;整数=
                    新的ArrayList＆LT;整数GT;（Arrays.asList（1,2,3,4,5））;
        插座S =新的Socket（）;
        s.connect（新的InetSocketAddress（本地主机，1234））;
        ObjectOutputStream的出=新的ObjectOutputStream（s.getOutputStream（））;
        out.writeObject（整数）;
        S.CLOSE（）;
    }    静态类服务器实现Runnable {
        公共无效的run（）{
            尝试{
                ServerSocket的服务器=新的ServerSocket（1234）;
                插座ClientSocket的= server.accept（）;
                ObjectInputStream中的=
                        新的ObjectInputStream（clientSocket.getInputStream（））;
                对象o = in.readObject（）;
                的System.out.println（接收服务器上的这个对象：+ O）;
                clientSocket.close（）;
                server.close（）;
                executorService.shutdown（）;
            }赶上（IOException异常五）{
                // TODO：收件箱
                抛出新UnsupportedOperationException异常（不写）;
            }赶上（ClassNotFoundException的E）{
                // TODO：收件箱
                抛出新UnsupportedOperationException异常（不写）;
            }
        }
    }
}
 

How can I send an arraylist through tcp in Java? I need to send an arraylist of integers, from client to server and vice verse.

Thanxx

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

public class SerializeOverSocket {

    private static ExecutorService executorService =
                    Executors.newSingleThreadExecutor();

    public static void main(String[] args) throws Exception {
        // Start a server to listen for a client
        executorService.submit(new Server());
        Thread.sleep(100);
        // Send an ArrayList from a client
        ArrayList<Integer> integers =
                    new ArrayList<Integer>(Arrays.asList(1,2,3,4,5));
        Socket s = new Socket();
        s.connect(new InetSocketAddress("localhost", 1234));
        ObjectOutputStream out = new ObjectOutputStream(s.getOutputStream());
        out.writeObject(integers);
        s.close();
    }

    static class Server implements Runnable {
        public void run() {
            try {
                ServerSocket server = new ServerSocket(1234);
                Socket clientSocket = server.accept();
                ObjectInputStream in =
                        new ObjectInputStream(clientSocket.getInputStream());
                Object o = in.readObject();
                System.out.println("Received this object on the server: " + o);
                clientSocket.close();
                server.close();
                executorService.shutdown();
            } catch (IOException e) {
                // TODO: Write me
                throw new UnsupportedOperationException("Not written");
            } catch (ClassNotFoundException e) {
                // TODO: Write me
                throw new UnsupportedOperationException("Not written");
            }
        }
    }
}
