What does abstract path means in java.io?
file, io, java, path
Solution
An abstract pathname is a `java.io.File` object and a pathname string is a `java.lang.String` object. Both reference the same file on the disk.
How do I know?
The first sentence of the Javadoc of `java.io.File` explains:
An abstract representation of file and directory pathnames.
It goes on to explain why:
User interfaces and operating systems use system-dependent pathname strings to name files and directories. This class presents an abstract, system-independent view of hierarchical pathnames.
Problem
In java doc about ``` File#getPath() ``` writes: ``` Converts this abstract pathname into a pathname string. ``` I try to write1 ``` File file3 = new File("D:\\work"); System.out.println(file3.getPath()); ``` In cmd I see `D:\\work` I try to write2: ``` File file4= new File("file4"); System.out.println(file4.getPath()); ``` In cmd I see: ``` file4 ``` Thus I have a question: What the difference between abstract pathname and pathname string ?
