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\flower.jpg
Output
Path: C:\Users\admin\Pictures\
File name: flower
Extension: jpg
import java.util.Scanner;
public class RAnsariFilepathSplit
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter full path: ");
String filepath = in.next();
char pathSep = '\\';
char dotSep = '.';
int pathSepIdx = filepath.lastIndexOf(pathSep);
System.out.println("Path:\t\t" + filepath.substring(0, pathSepIdx));
int dotIdx = filepath.lastIndexOf(dotSep);
System.out.println("File Name:\t" + filepath.substring(pathSepIdx + 1, dotIdx));
System.out.println("Extension:\t" + filepath.substring(dotIdx + 1));
}
}Enter full path: C:\Users\HP\Pictures\data-types.png
Path: C:\Users\HP\Pictures
File Name: data-types
Extension: png

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
