实现一个服务器，通过我们发送的文本数据，然后转回大写放回，实现一个服务端与客户端的交互，用over来作为结束标记，具体代码如下：
客户端：
package com.seven.tcp; import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.InputStreamReader; import java.io.OutputStreamWriter; import java.net.Socket; public class TranClient { public static void main(String[] args) throws Exception{ Socket socket = new Socket("127.0.0.1",10001); //文本数据，用字符流，读取键盘 BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); //负责写 BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())); //读取返回数据 BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream())); String line = null; while((line = reader.readLine())!=null){ if("over".equals(line)){ break; } writer.write(line); writer.newLine(); writer.flush(); System.out.println("server return :" + in.readLine()); } reader.close(); socket.close(); } }
服务端：
package com.seven.tcp; import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.InputStreamReader; import java.io.OutputStreamWriter; import java.net.ServerSocket; import java.net.Socket; public class TranServer { public static void main(String[] args) throws Exception { ServerSocket serverSocket = new ServerSocket(10001); Socket socket = serverSocket.accept(); //读取数据 BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream())); //写回数据 BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())); String line = null; while((line = reader.readLine())!=null){ writer.write(line.toUpperCase()); writer.newLine(); writer.flush(); } writer.close(); socket.close(); } }
这样子，就可以实现小写转大写，输入over就结束连接==。
