java - How to get the file location using the file path? -


in eclipse, when right click on file want input in project, shows 2 things: path: /swt/src/data.txt location: c:\users\yoshikawa\workspace\swt\src\data.txt

is there way can location (c:\users\yoshikawa\workspace\swt\src\data.txt) know path (/swt/src/data.txt) ?

ex. 

public string readfile(string file_path) {         //search current project directory               return file_location     } 

public string readfile(string file_path){   file f = new file(file_path);   return f.getabsolutepath(); }
