java入门---网络实例操作之获取本机ip地址及主机名

    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);
   }
}
