类名称：Argument
方法名：nargs

Argument.nargs介绍

[英]Sets the number of command line arguments that should be consumed.

Don't give this method '', '+' or '?'. They are converted to int value and it is not what you expect. For these strings, use #nargs(String).
[中]设置应使用的命令行参数数。
不要给这个方法“”、“+”或“？”。它们被转换为int值，这不是您所期望的。对于这些字符串，请使用#nargs（String）。
