网络编程socket实例

客户端：

class TrancClient{

Socket socketClient = new Socket("192.168.1.1",10005);

BufferedReader bufr = BufferedReader(new InputStreamReader(System.in));

BufferedWriter bufO= BufferedWriter(new OutputStreamWriter(socketClient.getOutputStream())));

BufferedReader bufIn = BufferedReader(new InputStreamReader(socketClient.getInputStream())));

//可以更改为下面这个流，里面自带flush和换行，已经字符集转换封装功能。

//PrintWriter out = new PrintWriter(socket.getInputStream()，true);

String readLine = null;

while(readLine=bufr.readLine())!=nulll){

if(readLine.equest("over')){

break;

}

out.write(readLine);

//用printWriter方式以下语句全部可以注释掉，只需要加上以上一句；

bufO.write(readLine);

bufO.newLine(); //如果是键盘输入，源，需要键入回车键，不然一直在等待状态中。

bufO.flush(); //在socket流中，需要通过flush来完成最终写出；不然有可能阻塞在里面；

}

class TrancServer{

ServerSocket ss = new ServerSocket(10005);

Socket serverSocket = ss.accept();

BufferedRead bufinput = BufferedReader(new InputStreamReader(serverSocket.getInputStream())));

BufferedWriter bufout = BufferedWriter(new OutputStreamWriter(serverSocket.getOutputStream())));

//可以更改为下面这个流，里面自带flush和换行，已经字符集转换封装功能。

//PrintWriter out = new PrintWriter(socket.getInputStream()，true);

String line = null;

while((line = bufinput.readLine)!= null){

bufout.writer(line.toUpdataCase()));

bufout.flush();

}

serverSocket.close();

ss.close();
