推荐答案

java.io.File 只是

文件和目录路径名的抽象表示.

An abstract representation of file and directory pathnames.

您必须使用 FileWriter / PrintWriter / BufferedWriter 在磁盘上创建实际的物理文件.

you have to use FileWriter/PrintWriter/BufferedWriter to create an actual physical file on the disk.

Sorta像这样:

String newFileName = "Temp" + fileName;
File newFile = new File(newFileName);
BufferedWriter writer = new BufferedWriter(new FileWriter(newFile));
