I am using MacBook. I have a file located under ~/temp/note.txt.

(~ represents home directory by default in terminal).

I want to access this file in my java code:

File fileDir = new File("~/temp");
// I get exist = false, why?
boolean exist = fileDir.exist();

But my java code can't find the directory ~/temp. I guess it is because java code can't recognize ~ ? How to make it work ?

  • Try ./ instead of ~/ if you are running this program from the home directory. If you want the home directory, you need to give the path explicitly – Chetan Kinger Feb 27 '15 at 11:13

  • An information I am missing in the other answers: `~` is parsed by the shell. The issue that it doesn't work exists in all (other) programming languages. – glglgl Feb 27 '15 at 11:23
  • Do you have a folder called `~`? No? That's why. (`~` is only a shortcut to save typing in your shell, it's not what the directory is actually called) – user253751 Feb 27 '15 at 11:33

May be you could use the system variables and concatenate with 'temp.txt'.
You could obtain your user home directory via : 

 System.getProperty("user.home")

If it's not ok, try 

System.getProperty("user.dir")

Hope this could help
