从java中删除文件夹[重复]

在Java中，我想删除包含文件和文件夹的文件夹中存在的所有内容。

public void startDeleting(String path) {
        List<String> filesList = new ArrayList<String>();
        List<String> folderList = new ArrayList<String>();
        fetchCompleteList(filesList, folderList, path);
        for(String filePath : filesList) {
            File tempFile = new File(filePath);
            tempFile.delete();
        }
        for(String filePath : folderList) {
            File tempFile = new File(filePath);
            tempFile.delete();
        }
    }

private void fetchCompleteList(List<String> filesList, 
    List<String> folderList, String path) {
    File file = new File(path);
    File[] listOfFile = file.listFiles();
    for(File tempFile : listOfFile) {
        if(tempFile.isDirectory()) {
            folderList.add(tempFile.getAbsolutePath());
            fetchCompleteList(filesList, 
                folderList, tempFile.getAbsolutePath());
        } else {
            filesList.add(tempFile.getAbsolutePath());
        }

    }

}

此代码不起作用，执行此操作的最佳方法是什么？

如果你使用Apache 公共 IO http://commons.apache.org/io这是一行：

FileUtils.deleteDirectory(dir);

See FileUtils.deleteDirectory() http://commons.apache.org/proper/commons-io///apidocs/org/apache/commons/io/FileUtils.html#deleteDirectory%28java.io.File%29

Guava http://code.google.com/p/guava-libraries used to support similar functionality:

Files.deleteRecursively(dir);
