为什么我在扫描仪上使用路径？

Question

Why I can just use the String adress, like "C:/Users/CleBo/IdeaProjects/test/status.txt" . Why I have show it in Path, like:

Path path = Paths.get ("C:/Users/CleBo/IdeaProjects/test/status.txt").

If I write System.out.println ("C:/Users/CleBo/IdeaProjects/test/status.txt") it will be the same thing if I write:

System.out.println(path);

What the different?

Answer 1

The String and Path overloads do different things:

• The String is the data the Scanner will tokenize. For example, if you call new Scanner("I'm a little teapot") , that scanner will return the tokens I'm , a , little and teapot .
• The Path is where to find the data for to be tokenized. For example, it points to a file containing the data. The tokens it returns will depend upon the contents of the file identified by that path.

Which one you use depends on your use case.
