File getAbsolutePath() method in Java with Examples

The getAbsolutePath() method is a part of File class. This function returns the absolute pathname of the given file object.If the pathname of the file object is absolute then it simply returns the path of the current file object.

For Example: if we create a file object using the path as “program.txt”, it points to the file present in the same directory where the executable program is kept (if you are using an IDE it will point to the file where you have saved the program ). Here the path of the file mentioned above is “program.txt” but this path is not absolute (i.e. not complete). The function getAbsolutePath() will return the absolute (complete) path from the root directories. If the file object is created with an absolute path then getPath() and getAbsolutePath() will give the same results.

Function Signature:



public String getAbsolutePath()

Function Syntax:

file.getAbsolutePath()

Parameters: This function does not accept any parameters.

Return value: This function returns a String value which is the absolute Path of the given File object.

Exception: This method throws Security Exception if the required property value cannot be accessed.

Below programs will illustrate the use of getAbsolutePath() method:

Example 1: A file named “program.txt” is in the present working directory.

            // Get the absolute path of file f
            String absolute = f.getAbsolutePath();
  
            // Display the file path of the file object
            // and also the file path of absolute file
            System.out.println("Original  path: "
                               + f.getPath());
            System.out.println("Absolute  path: "
                               + absolute);
        }
        catch (Exception e) {
            System.err.println(e.getMessage());
        }
    }
}

Output:

Original file path: f:\program.txt
Absolute file path: f:\program.txt

The programs might not run in an online IDE . please use an offline IDE and set the path of the file
