FileInputStream从特定位置读取文件？

Question

If I place text file in same project folder, program can read it without problems. But how can I make it read a file from somewhere in my computer (ex: in Desktop)

FileInputStream fstream = new FileInputStream("Contact.txt");

I change it to "C:...\\Desktop\\Contact.txt") but I getting error.

Answer 1

Change the backslash ( \\ ) to forwardslash( / ) or use double backslashes ( \\\\ ) in your file path.

  FileInputStream fstream = new FileInputStream("C:.../Desktop/Contact.txt");

or

  FileInputStream fstream = new FileInputStream("C:...\\Desktop\\Contact.txt");

Please Note: \\ is an escape character. If you use \\\\ , it will use single \\ as literal.

Answer 2

You should use File.separator instead of / and \\\\ to delimit your path as this is will work on both Window and Unix based systems. This might help to convince you...!
