Absolute path for a file in Java?

**260191894** · 06-13-2012, 04:43 PM

Hi everyone!

I am trying to write Java programs that can access files. Is there a way that my program can access a file no matter where it is in the system without knowing the location? Currently, the program can only upload the file if it is the same directory.

Thank you very much for your time!

Do you mean to locate a file in whole filesystem? Do you know how expensive could it be?

Actually my main filesystem (I have 3 filesystems plus the main) contains 584194 files.

Do you have any aditional information of the location of the file?

You always specify a path name: if you only specify the base name, the file has to be located in the 'current working directory', otherwise the path can be a relative path (and relative to this current working directory) or an absolute path name.

kind regards,

Jos

Hi Jos!

What does the absolute path name require?

Thank you!

Hi lilezek!

I want to use the absolute path but I don't know what it includes because when the compiler keeps saying "file not found".

Thank you!

Every path name starting with a '/' character is an absolute path name; Microsoft file systems know about more roots: "/C:", "D:" etc.

I am using Apple OSX with a user account. When I click on "get info" for a file, the system gives me /User/.... I assume that is the absolute path file?

Thank you!

It starts with a '/' character, so according to the definition, it's an absolute path name.
