找不到Java数据库路径 [英] Java database path not found

问题描述

我正在尝试更改eclipse java neon的文件路径以访问我的编程课程所需的数据库，但我不知道如何在Windows 10上做到这一点(这本书仅指导我们如何做在第8和7窗口中).

I'm attempting to change the file path of eclipse java neon to access a database I need for my programming class and I cant figure out how to do it for windows 10 (the book only instructs us on on how to do it in window 8 and 7).

我给你一个简短的版本，只是说这本书告诉我要么编辑当前的classpath看起来像.; C:\Program Files\Java\jdk1.7.0_51\db\lib\derby.jar，要么制作一个看起来像这样的新书.

I'll give you the short version and just say that the book tells me to either edit the current classpath to look something like .;C:\Program Files\Java\jdk1.7.0_51\db\lib\derby.jar or to make a new one that looks like that.

问题是，当我将其更改为时，它一直给我一个路径错误，我只需要修复该错误.我的Java版本是jre1.8.0_111，而database应该被称为CoffeeDB(尽管我认为您不需要该信息).

The problem is when I changed it to look like that it kept giving me a path error and I just need to fixed that error. My version of Java is jre1.8.0_111 and the database I am supposed to be making is called CoffeeDB (though I don't think you need that info).

最终的目的是能够连接到数据库，这样我就可以完成创建和更改数据库的工作.

The end game of this is to be able to connect to databases so I can do my homework of creating and changing them.

如果您需要更多信息来帮助我，而我不愿提供这些信息，我不确定您还需要什么.

If you need more information to help I am more than willing to give it, I'm just not sure as to what more you would need.
