使用Java将文件从一个目录移动到另一个目录-yiteyi-C++库

Java提供了在目录之间移动文件的功能。这里描述了实现这一点的两种方法。第一种方法利用文件包进行移动，而另一种方法首先将文件复制到目标，然后从源中删除原始副本。

null

使用文件。路径移动（）方法： 重命名文件并将其永久移动到新位置。 语法：

public static Path move(Path source, Path target, CopyOption..options)           throws IOExceptionParameters: source - the path to the file to movetarget - the path to the target file (may be associated with a different provider to the source path)options - options specifying how the move should be doneReturns: the path to the target file

输出：

File renamed and moved successfully

使用Java。伊奥。文件Rename to（）和Java。伊奥。文件delete（）方法： 使用这两种方法复制文件和删除原始文件。 Rename to（）的语法：

public boolean renameTo(File dest)Description: Renames the file denoted by this abstract path name.Parameters: dest - The new abstract path name for the named fileReturns: true if and only if the renaming succeeded; false otherwise

delete（）的语法：

public boolean delete()Description: Deletes the file or directory denoted by this abstract path name.Returns: true if and only if the file or directory is successfully deleted; false otherwise
