java如何获得当前ip地址

可使用InetAddress类中的getLocalHost()方法来获得当前IP地址。代码示例以下：

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
