推荐答案

有多种方法可以访问远程计算机上的文件，但它们几乎都依赖于已经设置了远程机器以首先以某种方式提供文件。如果您要通过java访问文件，最简单的方法可能是在远程计算机上设置HTTP服务器（这可以通过各种平台上的Apache HTTP服务器轻松完成），然后使用Apache Commons HTTPClient客户端Java应用程序。关于如何安装这些或配置它们的进一步讨论通常超出了Stack Overflow的范围，并且至少需要一个更具体的问题

There are any number of ways to access files on remote machines, but they virtually all depend on the remote machine having been set up to provide the file in some way first. If you with to access files via java, the easiest method would probably be to set up an HTTP server on the remote machine (this can be done pretty easily using Apache HTTP server on a variety of platforms) and then using Apache Commons HTTPClient on the client side java app. Further discussion of how to install these or configure them is generally beyond the scope of Stack Overflow and would at least require a more specific question
