Socket 发送long问题? 高手赐教 ..!!!!

[Even__Chung]

public static final long ACK_CONNECT_OK         = 0x0;        	
public static final long ACK_STOP_MCU           = 0x10;       
public static final long ACK_REV_FILEINFO	= 0x100;      
public static final long ACK_REV_FILE		= 0x1000;     
public static final long ACK_REV_UPGRADE_OK	= 0x10000;    
public static final long ACK_REV_MCU_OK		= 0x100000;   
public static final long ACK_REV_MCU_ERROR	= 0x100001; 

客户端 想建立一个 TCP 连接 向另一台电脑 IP 192.168.1.1 端口 8888 依次发送 以上 long 数据
并也接收服务端发来 long 的数据提示



小弟刚学Java
不知道怎么建立这个连接
怎么向另一台电脑发送数据包
前来csdn赐教
希望大哥大姐能给些代码 提示
感激不尽
分不多
我明天还会加分
明天结贴 ..

谢谢了

服务器端：

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class SocketServer {
    ServerSocket ss = null;

    Socket s = null;

    DataInputStream inStream = null;

    DataOutputStream outStream = null;

    public SocketServer() {
        try {
            init();
        } catch (Exception e) {
            System.out.println(e.toString());
        }
    }

    void init() throws Exception {
        ss = new ServerSocket(765);
        s.setSoTimeout(3000);
    }

    void waitForClient() {
        try {
            s = ss.accept();
            inStream = new DataInputStream(s.getInputStream());
            outStream = new DataOutputStream(s.getOutputStream());
            outStream.writeUTF("1");
            s.setSoTimeout(3000);
            waitData();
        } catch (Exception e) {
            System.out.println(e.toString());
        }
    }

    void waitData() {
        while (true) {
            try {
                String str = inStream.readUTF();
                System.out.println("Server accept: " + str);
                int nu = Integer.parseInt(str) + 1;
                if (nu > 20) {
                    System.out.println("Send end!");
                    break;
                } else {
                    str = Integer.toString(nu);
                    outStream.writeUTF(str);
                }
            } catch (Exception e) {
                System.out.println(e.toString());
                break;
            }
        }
    }

    public static void main(String[] args) {
        SocketServer socketServer1 = new SocketServer();
        socketServer1.waitForClient();
    }
}

客户端：

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.net.Socket;

public class SocketClient {
    Socket s = null;

    DataInputStream inStream = null;

    DataOutputStream outStream = null;

    public SocketClient() {
        try {
            init();
            waitData();
        } catch (Exception e) {
            System.out.println(e.toString());
        }
    }

    void init() throws Exception {
        s = new Socket("192.168.0.32", 765); // 把这里的IP改成你运行SocketServer.class的IP
        inStream = new DataInputStream(s.getInputStream());
        outStream = new DataOutputStream(s.getOutputStream());
        s.setSoTimeout(3000);
    }

    void waitData() {
        while (true) {
            try {
                String str = inStream.readUTF();
                System.out.println("Client accept: " + str);
                str = Integer.toString(Integer.parseInt(str) + 1);
                outStream.writeUTF(str);
            } catch (Exception e) {
                System.out.println(e.toString());
                break;
            }
        }
    }

    public static void main(String[] args) {
        SocketClient socketClient1 = new SocketClient();
    }
}

手里有个例子，参照这个改一下吧～～

思想就是服务器端用ServerSocket监听客户端的连接(红色所示)

void waitForClient() {
        try {
            s = ss.accept();
//sccept会阻塞，一直到有客户端连到此服务器端

客户端创建socket连接服务器，并通过流来发送数据，服务器端发现有客户端连接后就可以获取客户端传递的数据

上贴代码是2楼的，借用，解释下

[bzwm]

建立socket连接，
然后用DataInputStream的readLong 方法来接收
DataOutputStream 的writeLong方法去发送
