问题描述
共有两个类
foo.bar.FileUploader 和 barbar.foofoo .FileUploader
两者都是相同的，并扩展上传者
Both are identical and extend Uploader
在代码中，使用 foo.bar.FileUploader ，作为上传者类型。
Somewhere in the code the foo.bar.FileUploader is used and are given as a parameter to my function as an Uploader type.
现在我需要将它转回 FileUploader code> barbar.foofoo.FileUploader 。这会产生错误：
Now I need to cast it back to FileUploader but the barbar.foofoo.FileUploader. And this gives an error:
我不知道出了什么问题，我想这是因为包是不同的。在这种情况下：有没有办法仍然使用类并获得转换完成？
And I can't figure out what's going wrong, I suppose it's because the package is different. In that case: Is there a way to still use the class and get the cast done?
推荐答案
我刚刚通过导入barbar.foofoo.FileUploader来解决这个问题。现在它运行良好！
I just solved the problem by importing the the barbar.foofoo.FileUploader. Now it runs fine!
这篇关于如何转换类型的同一类，但从Java中的其他包？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
