本文整理了Java中java.net.Socket.isClosed()方法的一些代码示例，展示了Socket.isClosed()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Socket.isClosed()方法的具体详情如下：
包路径：java.net.Socket
类名称：Socket
方法名：isClosed

Socket.isClosed介绍

[英]Returns whether this socket is closed.
[中]返回此套接字是否已关闭。

代码示例

代码示例来源：origin: CarGuo/GSYVideoPlayer

private void closeSocket(Socket socket) {
  try {
    if (!socket.isClosed()) {
      socket.close();
    }
  } catch (IOException e) {
    //onError(new ProxyCacheException("Error closing socket", e));
  }
}

代码示例来源：origin: apache/zookeeper

public void flush() throws IOException {
  try {
    learner.writePacket(null, true);
  } catch(IOException e) {
    LOG.warn("Closing connection to leader, exception during packet send", e);
    try {
      if (!learner.sock.isClosed()) {
        learner.sock.close();
      }
    } catch (IOException e1) {
        // Nothing to do, we are shutting things down, so an exception here is irrelevant
        LOG.debug("Ignoring error closing the connection", e1);
    }
  }
}

Socket s = new Socket();

System.out.println("isConnected: " + s.isConnected() +
         " isBound: "     + s.isBound() +
         " isClosed: "    + s.isClosed());

s.connect(new InetSocketAddress("google.com", 80));

System.out.println("isConnected: " + s.isConnected() +
          " isBound: "    + s.isBound() +
          " isClosed: "   + s.isClosed());

s.close();

System.out.println("isConnected: " + s.isConnected() +
