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。

package com.hy.csdn.tools;import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;/*** @Program: hy-utils @ClassName: StuNetworkInterface @Author: huyi @Date: 2020-09-20* 23:48 @Description: 网络接口 @Version: V1.0*/
public class NetworkInterfaceUtil {public static void main(String[] args) {try {Enumeration<NetworkInterface> networkInterfaces = NetworkInterface.getNetworkInterfaces();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("getIndex获得网络接口的索引=" + networkInterface.getIndex());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。
