A full path and file name

Write a program to assign a full path and file name as given below. Using library functions, extract and output the file path, file name and file extension separately as shown.

Input: C:Users\admin\Pictures\flowers.jpg
Output:
Path: C:Users\admin\Pictures
File name: flower
Extension: jpg

import java.io.*;

class File_Q6_ICSE2014

    {

    public static void main(String args[])throws IOException

        {

            BufferedReader br=new BufferedReader (new InputStreamReader(System.in));

            System.out.print("Enter the full path of the file : ");

            String s = br.readLine();

             

            int x = s.lastIndexOf('\\'); // Finding position of last backward slash

            int y = s.lastIndexOf('.'); // Finding position of last '.'

             

            String path = s.substring(0,(x+1));

            String file = s.substring((x+1),y);

            String extn = s.substring((y+1));

             

            System.out.println("Output :");

            System.out.println("Path : "+path);

            System.out.println("File Name : "+file);

            System.out.println("Extension : "+extn);

        }

    }




Note: For extracting the position of backslash, ” is not valid as is an escape character in java and is treated differently. So in order to override this we are have to use ” instead of ”




Output:

Enter the full path of the file : C:Users\Java\awesome.txt
Output :
Path : C:Users\Java
File Name : awesome
Extension : txt
