InetAddress的使用

public class Test01 {
    public static void main(String[] args) throws UnknownHostException{
        //获取本机inetAddress对象
        InetAddress address=InetAddress.getLocalHost();
        System.out.println("计算机名： "+address.getHostName());
        System.out.println("IP地址： "+address.getHostAddress());
        byte[] bytes=address.getAddress();
        System.out.println("字节数组形式的IP： "+ Arrays.toString(bytes));
        System.out.println(address);
        //获取指定IP或者名称的inetAddress对象
        InetAddress address2=InetAddress.getByName("115.196.153.44");
        System.out.println("计算机名： "+address2.getHostName());
        System.out.println("IP地址： "+address2.getHostAddress());
    }
}
