Dump files contain a snapshot of your program's state at some point in time, usually after a crash.

Running this command tells the JVM to take a "heap dump snapshot" and save it to a file for processing, usually using the jhat utility (which I introduced in a previous article).
運(yùn)行該命令通知 JVM 拍攝一個 “堆轉(zhuǎn)儲快照”，竝將其保存在一個文件中以便処理，通常使用 jhat 實(shí)用工具（我在上一篇文章中介紹過）。
