Extension: jpg
Answer
import java.util.Scanner;
public class KboatFilepathSplit
{
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));
}
}Output
