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。
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。
