 Main.java

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
