Problem with relative file path

Question

So here is my program, which works ok:

import java.io.FileReader;
import java.io.BufferedReader;
import java.io.IOException;
import java.util.Scanner;
import         


        

Answer 1

It must be a FileNotFoundException causing NPE in the finally block. Eclipse, by default, executes the class with the project folder (D:/java-projects/HelloWorld in your case ) as the working directory. Put the usnumbers.txt file in that folder and try. Or change the working directory in Run Configuration -> Argument tab
