期末考-android client server

import java.io.BufferedInputStream;

import java.io.BufferedOutputStream;

import java.io.IOException;

import java.net.ServerSocket;

import java.net.Socket;

public class tcpserver {

/**

* @param args

*/

public static void main(String[] args) {

// TODO Auto-generated method stub

byte[] data = new byte[1024];

int temp;

try {

ServerSocket server0 = new ServerSocket(3334);

Socket socket = server0.accept();

BufferedInputStream bin = new BufferedInputStream(socket.getInputStream());

while((temp = bin.read())!= -1){

System.out.print((char)temp);

}

bin.close();

server0.close();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

try {

ServerSocket server1 = new ServerSocket(3335);

Socket socket = server1.accept();

BufferedInputStream bin = new BufferedInputStream(socket.getInputStream());

while((temp = bin.read())!= -1){

System.out.print((char)temp);

}

bin.close();

server1.close();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

===============================================================

以上這邊是Server的程式部分,基本上與上課的大同小異,重點在於要在建立起一個新的Port 讓Client能夠同時連線...所以直接把中間那段,再見port的程式複製之後貼在下面,把port改3335,Server的部分就完成了...

===============================================================

至於Client的部分,也是利用上課的範例,把資料夾名稱改掉,再把專案載入進來,這樣就有兩個client的專案,一樣把第二個專案連結port的地方改掉,再把要輸出的字也改掉,就完成了..

=========================

package tw.brad.tcpclient;

import java.io.BufferedOutputStream;

import java.io.IOException;

import java.net.Socket;

import java.net.UnknownHostException;

import android.app.Activity;

import android.os.Bundle;

public class tcpclient extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

byte[] buffer = "This is client1".getBytes();

try {

Socket socket = new Socket("10.0.2.2", 3334);

BufferedOutputStream bout =

new BufferedOutputStream(socket.getOutputStream());

bout.write(buffer);

bout.flush();

bout.close();

socket.close();

} catch (UnknownHostException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

==========================

以上為client1

==========================

package tw.brad.tcpclient;

import java.io.BufferedOutputStream;

import java.io.IOException;

import java.net.Socket;

import java.net.UnknownHostException;

import android.app.Activity;

import android.os.Bundle;

public class tcpclient extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

byte[] buffer = "\n This is client2".getBytes();

try {

Socket socket = new Socket("10.0.2.2", 3335);

BufferedOutputStream bout =

new BufferedOutputStream(socket.getOutputStream());

bout.write(buffer);

bout.flush();

bout.close();

socket.close();

} catch (UnknownHostException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

====================

以上為Client2
