本文整理了Java中org.openide.filesystems.FileUtil.getConfigFile()方法的一些代码示例，展示了FileUtil.getConfigFile()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。FileUtil.getConfigFile()方法的具体详情如下：
包路径：org.openide.filesystems.FileUtil
类名称：FileUtil
方法名：getConfigFile

FileUtil.getConfigFile介绍

[英]Returns FileObject from the NetBeans default (system, configuration) filesystem or null if does not exist. If you wish to create the file/folder when it does not already exist, start with #getConfigRoot and use #createData(FileObject,String)or #createFolder(FileObject,String) methods.
[中]从NetBeans默认（系统、配置）文件系统返回FileObject，如果不存在则返回null。如果希望在文件/文件夹不存在时创建它，请从#getConfigRoot开始，并使用#createData（FileObject，String）或#createFolder（FileObject，String）方法。
