Answer 1

import java.net.*;
public class Test {
public static void main(String[] args) throws Exception {
String ip = InetAddress.getLocalHost().getHostAddress();
System.out.println(ip);
}
}

Answer 2

《java》中提取本地IP的方法如下：

private static void getIpAddressByNetworkInterface() {

try {

Enumeration<NetworkInterface> nets = NetworkInterface.getNetworkInterfaces();    

NetworkInterface net;

InetAddress inetAddress;

while (nets.hasMoreElements()) {

net = nets.nextElement();

Enumeration<InetAddress> address = net.getInetAddresses();

while (address.hasMoreElements()) {

inetAddress = address.nextElement();

if (inetAddress!=null&&inetAddress instanceof Inet4Address)

System.out.println(inetAddress.getHostAddress());

}

}

} catch (SocketException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

Answer 3

InetAddress.getLocalHost();
