本文整理了Java中net.sourceforge.argparse4j.inf.ArgumentParser类的一些代码示例，展示了ArgumentParser类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ArgumentParser类的具体详情如下：
包路径：net.sourceforge.argparse4j.inf.ArgumentParser
类名称：ArgumentParser

ArgumentParser介绍

[英]This interface defines behavior of ArgumentParser.

The typical usage is set description using #description(String) and add arguments using #addArgument(String...). To add sub-command, first call #addSubparsers() to obtain Subparsers object. Subparsers object provides necessary methods to add sub-commands. To make a conceptual group of arguments, first call #addArgumentGroup(String) to create ArgumentGroup object. And add argument to that group using ArgumentGroup#addArgument(String...). Similarly, to add the mutually exclusive group of arguments, use #addMutuallyExclusiveGroup(String) to create MutuallyExclusiveGroup object. To parse command-line arguments, call #parseArgs(String[]) or several overloaded methods.
[中]此接口定义ArgumentParser的行为。
典型用法是使用#description（字符串）设置description，并使用#addArgument（字符串…）添加参数。要添加sub命令，首先调用#addSubparsers（）以获取Subparsers对象。Subparsers对象提供了添加sub命令的必要方法。要创建参数的概念组，首先调用#addArgumentGroup（String）来创建ArgumentGroup对象。并使用ArgumentGroup#addArgument（字符串…）将参数添加到该组。类似地，要添加互斥的参数组，请使用#addMutuallyExclusiveGroup（字符串）创建MutuallyExclusiveGroup对象。要解析命令行参数，请调用#parseArgs（String[]）或几个重载方法。
