技術標籤：TCP協議java

使用TCP協議將使用者傳送的資訊接收並儲存

客戶端：

Socket socket = null;
			try {
				 socket = new Socket(InetAddress.getByName("10.17.128.82"), 12439);
				OutputStream outputStream = socket.getOutputStream();	
				Scanner sc= new Scanner(System.in);
				String str = sc.nextLine();//獲取鍵盤輸入
				byte
 
[] buf = str.getBytes();
				outputStream.write(buf);//傳送要儲存的資料
				System.out.println("資料已經發送");		
			} catch (Exception e) {
				e.printStackTrace();
			}finally {
				try {
					socket.close();//關閉資源
				} catch (IOException e) {
					e.printStackTrace();
				}
			}		
		}

服務端：

while(true) {
 

		ServerSocket serverSocket = null;
		FileOutputStream fileOutputStream = null;
		File file = new File("src\\file\\paper.txt");
		byte buf[] = new byte[1024];
		try {
				    serverSocket = new ServerSocket(12439);
					Socket accept = serverSocket.accept();
					InputStream inputStream = accept.
 
getInputStream();//獲取輸入流
					inputStream.read(buf);//讀取資料，資料在buf陣列中
					serverSocket.close();//關閉資源
					fileOutputStream = new FileOutputStream(file);
					fileOutputStream.write(buf);
					System.out.println("接收到的資料已經寫入txt檔案中");
			
		} catch (IOException e) {
			e.printStackTrace();
		}finally {
			try {
				fileOutputStream.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
	}

結果：
