How to rename an existing file

Question

我的硬盘中有一个现有文件，我想重命名该文件。

Answer 1

像这样：

new File(path).renameTo(new File(newPath));

Answer 2

You may look at commons-io FileUtils.moveFile . That method tries File.renameTo , and if that fails, tries to copy&delete the file (eg when moving from one drive to another).

If you use File.renameTo directly (which should suffice if you only want to rename a file in the same directory), make sure you evaluate the returned boolean value!
