Java 中InetAddress类的详解

public class InetAddressDemo {
    public static void main(String[] args) {
        try {
        //确定主机名称的IP地址，主机名称可以是机器名称，也可以是IP地址
        //一般都是用IP地址
          //InetAddress byName = InetAddress.getByName("DESKTOP-4MSKKT0");
            InetAddress byName = InetAddress.getByName("192.168.0.124");
            //获取此IP地址的主机名
            String hostName = byName.getHostName();
            //返回文本显示中的IP地址字符串
            String ip = byName.getHostAddress();
            System.out.println("主机名：" + hostName);
            System.out.println("IP地址：" + ip);
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
    }
