import java.util.Scanner;
public class FileName {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter file name and path: ");
String input = scanner.nextLine();
int indexOfLastBackslash = input.lastIndexOf('\\');
int indexOfDot = input.lastIndexOf('.');
String outputPath = input.substring(0, indexOfLastBackslash + 1);
String fileName = input.substring(indexOfLastBackslash + 1, indexOfDot);
String extension = input.substring(indexOfDot + 1);
System.out.println("Path: " + outputPath);
System.out.println("File Name: " + fileName);
System.out.println("Extension: " + extension);
