java - new File(path, filename) 的path路径，是什么路径？

Question

path为“D:temptest”时，拿不到文件，但是为“D:\temptest”时可以?
关于路径的知识可以讲详细一些

Answer 1

is the path symbol. You can open a file and look at its path. This is how it is represented. This is specified by the operating system. If you have used linux, you will find that it uses /

Answer 2

I don’t know which version of Java you are using. In my local 1.7, the two writing methods are the same and both can get the file.
