JAVA ServerSocket 一个tip点

BucketLi

ServerSocket关了之后不会对已建立的Socket有任何影响
static void testSocket() throws Exception {      InetAddress ia = InetAddress.getByName("127.0.0.1");      ServerSocket ss = new ServerSocket();      ss.bind(new InetSocketAddress(ia, 0));      Socket s1 = new Socket();      s1.connect(new InetSocketAddress(ia, ss.getLocalPort()));      OutputStream os = s1.getOutputStream();      os.write(10);      Socket s2 = ss.accept();      ss.close();      InputStream is = s2.getInputStream();      System.out.println(is.read());            os.write(20);      System.out.println(is.read());}
