推荐答案

您可能需要遍历子网中的所有地址，然后向该地址发送"ping".如果它响应，则您知道该地址处有一个设备.我不知道如何找到设备上的操作系统.

You would probably need to loop through all the addresses in your subnet and send a ''ping'' to the address. If it responds then you know there is a device at that address. I don''t know how you could find out what OS is on the device.

您可以ping子网的广播地址，然后在命令行上调用"arp -a" .确保您使用的实际广播地址不只是255.255.255.255，否则ping会给您一个错误(在Windows计算机上).

由于您要求提供代码示例，因此我将您链接到此 [

You can ping the broadcast address of the subnet and then call "arp -a" on the command line. Make sure you use the actual broadcast address not just 255.255.255.255 or ping will give you an error (on a windows machine).

Since you asked for a code example I''ll link you to this[^], which shows how to use the OS command line interface from Java. I don''t think Java has native support for a ping class or an arp command. However, I think the ping and arp commands are the same for Windows, Unix, and Linux, at least for what you want to do.
