java網路編程(6)——實現一個伺服器把小寫轉大寫

標籤：

　　實現一個伺服器，通過我們發送的文本資料，然後轉回大寫放回，實現一個服務端與用戶端的互動，用over來作為結束標記，具體代碼如下：

用戶端：

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);                //文本資料，用字元流，讀取鍵盤        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));        //負責寫        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));        //讀取返回資料        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();                        }}

服務端：

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();        //讀取資料        BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));        //寫回資料        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();            }    }

這樣子，就可以實現小寫轉大寫，輸入over就結束串連==。
