以下实例演示了如何使用 InetAddress 类的 getLocalAddress() 方法获取本机ip地址及主机名：
import java.net.InetAddress;
public class Main {
public static void main(String[] args)
throws Exception {
InetAddress addr = InetAddress.getLocalHost();
System.out.println("Local HostAddress:
"+addr.getHostAddress());
String hostname = addr.getHostName();
System.out.println("Local host name: "+hostname);
}
}以上代码运行输出结果为：
Local HostAddress: 192.168.1.4 Local host name: harsh
