java - 为什么 new File ("c:\\a") 不等于 new File ("c:\\a","\\")？

Question

这些彼此相等:

new File("c:\\a")
new File("c:\\a\\")
new File("c:\\a","")
new File("c:\\a\\","")

但是 new File("c:\\a","\\")不等于他们

但是 new File("c:\\a","\\b")等于new File("c:\\a","b")

为什么？

Answer 1

JavaDocs for java.io.File 应该清楚这一点。

File(File parent, String child)
          Creates a new File instance from a parent abstract pathname and a child pathname string.
File(String pathname)
          Creates a new File instance by converting the given pathname string into an abstract pathname.
