如何在另一个 zip 中创建 zip。我得到了 fileNotFoundException

Question

如何在 zip 文件中创建 zip enter image description here

得到以下错误：

D:\sagar\my work\Package Maker\DirectoryStruct>java zipStructure
java.io.FileNotFoundException: Additional_Sub_Folder\Additional_file.zip (The sy
stem cannot find the path specified)
        at java.io.FileOutputStream.open(Native Method)
        at java.io.FileOutputStream.<init>(FileOutputStream.java:221)
        at java.io.FileOutputStream.<init>(FileOutputStream.java:110)
        at zipStructure.main(zipStructure.java:22)

D:\sagar\my work\Package Maker\DirectoryStruct> 即 Additional_sub_folder 和 Digital_sub_folder。在 Additional_sub_folder 1 中创建了 zip 文件（Additional_file.zip），在该 zip 2 文件夹中创建了 xml 文件夹和 pdf 文件夹

在 Digital_sub_folder 中创建 Artical_sub_folder，并在 Artical_sub_folder 中创建 3 个新文件夹，即 xml 文件夹、pdf 文件夹和 Graphics 文件夹。我尝试在java代码下面但不能正常工作，请帮助创建这个结构。

Answer 1

我没有遇到 zip-I/O 的问题，对于使用文件系统的每种类型的 I/O，我都有 FileNotFoundException。 对我有帮助的是，如果您使用 eclipse，则有“刷新项目”之类的功能或类似的功能。每次我遇到 I/O 问题时，它都有效。
