读万卷书不如行万里路，只学书上的理论是远远不够的，只有在实践中才能获得能力的提升，本篇文章手把手带你用Java获取网络接口的信息,大家可以在过程中查缺补漏，提升水平

前言

查看本机的网络接口信息，本文有详细的介绍哦。

代码

不废话，上代码。

      while (networkInterfaces.hasMoreElements()) {
        NetworkInterface networkInterface = networkInterfaces.nextElement();
        System.out.println("getName获得网络设备现实名称=" + networkInterface.getName());
        System.out.println("getDisplayName获得网络设备现实名称=" + networkInterface.getDisplayName());

        System.out.println("isUp是否已经开启并运行=" + networkInterface.isUp());
        System.out.println("isLoopback是否为回调接口=" + networkInterface.isLoopback());
        System.out.println("getMTU获得最大传输单元=" + networkInterface.getMTU());
        Enumeration<InetAddress> enumerations = networkInterface.getInetAddresses();
        while (enumerations.hasMoreElements()) {
          InetAddress inetAddress = enumerations.nextElement();
          System.out.println("获取此IP地址的完全限定域名=" + inetAddress.getCanonicalHostName());
          System.out.println("获取此IP地址的主机名=" + inetAddress.getHostName());
          System.out.println("获取此IP地址的字符串=" + inetAddress.getHostAddress());
          System.out.print("getAddress返回此InetAddress对象的原始IP地址=");
          byte[] addressByte = inetAddress.getAddress();
          for (byte b : addressByte) {
            System.out.print(b + " ");
          }
          System.out.println();
        }
        System.out.println();
      }
    } catch (SocketException e) {
      e.printStackTrace();
    }
  }
}

看看执行结果。
