本文整理了Java中java.io.File.getCanonicalFile()方法的一些代码示例，展示了File.getCanonicalFile()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。File.getCanonicalFile()方法的具体详情如下：
包路径：java.io.File
类名称：File
方法名：getCanonicalFile

File.getCanonicalFile介绍

[英]Returns a new file created using the canonical path of this file. Equivalent to new File(this.getCanonicalPath()).
[中]返回使用此文件的规范路径创建的新文件。等效于新文件（this.getCanonicalPath（））。

代码示例

public static boolean isSubdirectoryOf(File parent, File subdirectory) throws IOException {
  File parentFile = parent.getCanonicalFile();
  File current = subdirectory.getCanonicalFile();
  while (current != null) {
    if (current.equals(parentFile)) {
      return true;
    }
    current = current.getParentFile();
  }
  return false;
}
