在CommandLineParser 上定义的方法采用一个实例和参数和 返回命令行。parseOptionsString[] 解析阶段的结果是一个实例。CommandLine 1.3.审讯阶段 询问阶段是应用程序查询以决定执行分支的位置 根据布尔选项获取并使用选项值 以提供应用程序数据。CommandLine 此阶段在用户代码中实现。访问器方法 提供审讯功能 到用户代码。
The most significant thing in Rop is theOptionParserclass, with which Commands are registered, then you call itsparse()method to parse the command line arguments. The@CommandAnnotation Any vanilla class can be turned to a valid Command with the@Commandannotation, regardless it has Options or not...

例如,只需一行代码即可创建一个符合 POSIX 规范的命令行参数解析器: ```java CommandLineParser parser = new PosixParser(); ``` 为了更好地展示 Commons CLI 的功能和用法,通常会结合更多的代码示例,帮助开发者理解如何在实际项目中实现命令行参数的处理。 ### 关键词 Commons CLI, Java编程, 命令行, 参数...
