当你传递带空格的命令行参数时，它们被视为空格分隔的参数，并且是分裂在太空上。所以，你实际上没有一个参数，而是多个参数。

When you pass command line arguments with spaces, they are taken as space separated arguments, and are splitted on space. So, you don't actually have a single argument, but multiple arguments.

如果你想用空格传递参数，请使用引号：

If you want to pass arguments with spaces, use quotes:

java classname "Apple Inc. 2013 Jul 05 395.00 Call"
