java如何获取linux的ip地址

在Java中获取Linux系统的IP地址可以通过以下几种方法：

import java.net.InetAddress;import java.net.UnknownHostException;public class GetIPAddress {    public static void main(String[] args) {        try {            InetAddress address = InetAddress.getLocalHost();            System.out.println("IP Address: " + address.getHostAddress());        } catch (UnknownHostException e) {            e.printStackTrace();        }    }}

import java.net.InetAddress;import java.net.NetworkInterface;import java.util.Enumeration;public class GetIPAddress {    public static void main(String[] args) {        try {            Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();            while (interfaces.hasMoreElements()) {                NetworkInterface networkInterface = interfaces.nextElement();                Enumeration<InetAddress> addresses = networkInterface.getInetAddresses();                while (addresses.hasMoreElements()) {                    InetAddress address = addresses.nextElement();                    if (!address.isLoopbackAddress() && address.getHostAddress().indexOf(":") == -1) {                        System.out.println("IP Address: " + address.getHostAddress());                    }                }            }        } catch (Exception e) {            e.printStackTrace();        }    }}

这两种方法都可以获取Linux系统的IP地址，其中第一种方法是获取本地主机的IP地址，而第二种方法则是获取所有网络接口的IP地址。根据你的需求选择合适的方法获取IP地址即可。
