Java网络编程

在Java中使用InetAddress类代表IP

实例化InetAddress:两个方法：getByName(String host) 、 getLocalHost()两个常用方法：getHostName() / getHostAddress()

try {
            //File file = new File("hello.txt");
            InetAddress inet1 = InetAddress.getByName("192.168.10.14");

            System.out.println(inet1);

            InetAddress inet2 = InetAddress.getByName("www.atguigu.com");
            System.out.println(inet2);

            InetAddress inet3 = InetAddress.getByName("127.0.0.1");
            System.out.println(inet3);

            //获取本地ip
            InetAddress inet4 = InetAddress.getLocalHost();
            System.out.println(inet4);

            //getHostName()
            System.out.println(inet2.getHostName());
            //getHostAddress()
            System.out.println(inet2.getHostAddress());

        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
