推荐答案

Java Web Start 专门用于此目的。您运送一个jnlp文件，java负责从服务器获取最新版本。

Java Web Start is meant specifically for this. You ship one jnlp file, and java takes care of fetching the newest version from a server.

除此之外，您还可以下载更新的类并在运行时替换它们。

Apart from that, you can download updated classes and replace them at runtime.
