我是Java的新手，我使用运行时exec在linux中使用java运行命令。我期待找到一个命令让所有网络适配器在每个适配器上找到ip并将它们全部带到数组。
我该怎么做？
谢谢！

您显然可以运行ifconfig并解析输出，但为什么要这样做？
根据示例，使用NetworkInterface：
public static void main(String args[]) throws SocketException {
Enumeration<NetworkInterface> nets = NetworkInterface.getNetworkInterfaces();
for (NetworkInterface netint : Collections.list(nets))
displayInterfaceInformation(netint);
}
static void displayInterfaceInformation(NetworkInterface netint) throws SocketException {
out.printf("Display name: %s\n", netint.getDisplayName());
out.printf("Name: %s\n", netint.getName());
Enumeration<InetAddress> inetAddresses = netint.getInetAddresses();
for (InetAddress inetAddress : Collections.list(inetAddresses)) {
out.printf("InetAddress: %s\n", inetAddress);
}
out.printf("\n");
}
输出（我有很多虚拟接口）：

通过将示例更改为：
，您可以轻松过滤出虚拟的非虚拟接口for (NetworkInterface netint : Collections.list(nets)) {
if (!netint.isVirtual() && netint.isUp()) {
displayInterfaceInformation(netint);
}
}

我设法使用以下方法解决了这个问题：
for (NetworkInterface ni : Collections.list(NetworkInterface.getNetworkInterfaces())) {
for (InetAddress address : Collections.list(ni.getInetAddresses())) {
if (address instanceof Inet4Address) {
String ipadr = address.toString().replaceAll("/", "");
ipadr = ipadr.replaceAll("127.0.0.1", "");
if (!ipadr.equalsIgnoreCase("")) {
ipss.add(ipadr);
}
}
}
}
