350 TCP通信程序练习2（客户端数据来自于键盘录入）
【练习2】
客户端，数据来自键盘录入，直到输入886，则发送数据结束
服务器，接收数据，写屏
（自己尝试写了一遍，报错了，以下依次是原代码cilent、server，自己的代码client、server）
---------------------------------------------
package TCPPra2;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;
public class ServerDemoOriginalEdition {
public static void main(String[] args) throws IOException {
ServerSocket ss = new ServerSocket(10086);
Socket s = ss.accept();
//获取输入流
InputStream is = s.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
// 在client端，写数据是一次写一个字符串，在server端能不能一次读一个字符串？
// 能，用字符流，通过转换流把字节流转成字符流
// 以上3行代码，可以简化为1行
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
ss.close();
}
}

package TCPPra2;
import java.io.*;
import java.net.Socket;
public class ClientDemoOriginalEdition {
public static void main(String[] args) throws IOException {
Socket s = new Socket("192.168.43.241", 10086);
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
// 封装输出流对象，以便？
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
String line;
while ((line = br.readLine()) != null) {
if ("886".equals(line)) {
break;
}
// OutputStream os = s.getOutputStream();
// os.write(line.getBytes());
// 上句可以一次写一个数组，如果要一次写一个字符串呢？
// ——那就封装输出流对象，使用字符流写数据
bw.write(line);
bw.newline();
bw.flush();
}
}
