java - 无法在java中创建文件路径

Question

我正在尝试将我的文件保存到特定目录中。但我得到以下异常

Exception in thread "main" javax.xml.transform.TransformerException: java.io.FileNotFoundException: D:\News\nxis\NewFiles\I0cbf74105a2d11e5b730aca98fc673fd.nxi (The system cannot find the path specified)

这里真正可用的路径是

    String output = "D:\\News\\nxis\\" + replaceGuid + ".nxi";

但我正在尝试在其中添加一个新文件夹。我正在使用以下命令

    String output = "D:\\News\\nxis\\New Folder" + replaceGuid + ".nxi";

当我用第二步运行我的程序时。它给我一个错误。请告诉我如何解决它。

谢谢

这将解决您的问题:

new File(output).mkdir();

mkdir() 创建以此抽象路径名命名的目录。
