ServerSocket和Socket创建一个简易的服务器

1.Socket:

Socket socket=new Socket();

socket.connect(new InetSocketAddress("time-A.timefreq.bldrdoc.gov", 13), 1000);

InputStream inputStream = socket.getInputStream();

Scanner scanner = new Scanner(inputStream);

while(scanner.hasNextLine())

{

System.out.println(scanner.nextLine());

}

2.InetAddress:

a) 根据主机名获取其下所有的主机地址：

InetAddress[] addresses=InetAddress.getAllByName(hostName);

for(InetAddress inetAddress : addresses)

{

System.out.println(inetAddress);

}

b) 获取本地主机地址：

InetAddress address=InetAddress.getLocalHost();

System.out.println(address);

3.构建一个简单的服务器客户端：
