java怎么获取当前ip地址

可以使用InetAddress类中的getLocalHost()方法来获取当前IP地址。代码示例如下：

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("当前IP地址：" + address.getHostAddress());        } catch (UnknownHostException e) {            e.printStackTrace();        }    }}

运行结果：

当前IP地址：192.168.0.100
