Socket&ServerSocket類API

Socket用戶端套接字

//	構造方法
//	使用主機名和端口建立
public Socket(String host, int port)

//	成員方法
//	傳回Socket的輸入流
public InputStream getInputStream()

//	傳回Socket的輸出流
public OutputStream getOutputStream()

//	關閉Socket
public void close()

//	禁用Socket輸出流(方法調用前的資料發送,之後的都終止發送)
public void shutdownOutput()
           

ServerSocket服務端套接字

//	構造方法
public ServerSocket(int port)

//	成員方法
//	監聽并接受連接配接請求,傳回Socket對象
public Socket accept()
           

舉例

//	用戶端
public class TCPClient {
	public static void main(String[] args) {
		Socket socket = new Socket("localhost", 6666);
		OutputStream outputStream = socket.getOutputStream();
		String msg = "Hello TCP/IP";
		outputStream.write(msg.getBytes());
		outputStream.close();
		socket.close();
	}
}
//	服務端
public class TCPServer {
	public static void main(String[] args) {
		//	建立ServerSocket,監聽6666端口
		ServerSocket serverSocket = new ServerSocket("6666");
		Socket socket = serverSocket.accept();
		InputStream inputStream = socket.getInputStream();
		byte[] bytes = new byte[1024];
		int len = inputStream.read(bytes);
		String msg = new String(bytes, 0, len);
		System.out.println(msg);
		inputStream.close();
		socket.close();
		serverSocket.close();
	}
}
//	Hello TCP/IP
