delete() method check if it’s empty or not. If directory is empty, it gets deleted elsedelete()method doesn’t do anything and return false. So in this case, we have to recursively delete all the files and then the empty directory. 如果要删除目录,它将检查java File delete()方法是否为...
}elseif(files[i].isDirectory()) {//通过递归方法删除子目录的文件deleteAll(files[i]); } files[i].delete();//删除子目录} } }
2. UsingFiles.delete()from Java NIO Another approach in Java documentation is to useFiles.walkFileTree()to iterate over all the sub-directories and files in a given directory and delete them one by one. It works in two steps recursively: ...
deleteAllFilesOfDir(file);System.out.println("删除成功！！");} //递归删除文件夹(方法一)public static void deleteFile(File file) { if (file.exists()) {//判断文件是否存在 if (file.isFile()) {//判断是否是文件 file.delete();//删除文件 } else if (file.isDirectory()) {//...
java.io.File类有个有意思的方法deleteOnExit,这个方法的用途简单说就是要求在java虚拟机结束的时候删除该文件/目录。 删除文件,很好理解,结束的时候这个文件自动被删除;但是对于目录,我们知道,目录是可以层层嵌套的,对于一个有多级子目录的File对象?如何确保使用deleteOnExit被准确删除呢?
Files.walk(pathToBeDeleted) .sorted(Comparator.reverseOrder()) .map(Path::toFile) .forEach(File::delete); assertFalse("Directory still exists", Files.exists(pathToBeDeleted)); }Copy Here,Files.walk()returns aStreamofPaththat we sort in reverse order. This places the paths denoting the cont...
void deleteDirectory(file):deletes a directory recursively. It returnsIOExceptionin case the deletion is unsuccessful. boolean deleteQuietly(file):deletes a file without ever throwing an exception. If the file is a directory, delete it and all sub-directories. Itdoes not require the directory to...
如果不需要推送进度的话,可以直接调用Files.copy(source, out)方法进行复制文件。 7. 删除文件 File filePath =newFile("D:/home/logs/backupsystem_error.log");booleanresult = filePath.delete();//true表示删除成功System.out.println(result);
