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
