在这个例子中，我们将看到如何获得系统的 IP 地址。步骤如下：
1）通过调用InetAddress类的getLocalHost()方法获取本地主机地址。
2）通过调用getHostAddress()方法获取 IP 地址。
import java.net.InetAddress;class GetMyIPAddress{ public static void main(String args[]) throws Exception { /* public static InetAddress getLocalHost() * throws UnknownHostException: Returns the address * of the local host. This is achieved by retrieving * the name of the host from the system, then resolving * that name into an InetAddress. Note: The resolved * address may be cached for a short period of time. */ InetAddress myIP=InetAddress.getLocalHost(); /* public String getHostAddress(): Returns the IP * address string in textual presentation. */ System.out.println("My IP Address is:"); System.out.println(myIP.getHostAddress()); }}
输出：
My IP Address is:115.242.7.243
