Cant Get My Program to Read a Text File

Question

import java.util.Scanner;
import java.io.*;
import java.text.DecimalFormat;
public class Calculator
    public static void main (String[] args)
        final String filepath = "calculator.txt";
        int a, b, x;
        String command;
        Scanner fileScan = new Scanner(new File(filepath));
        while (fileScan.hasNext())
            command = fileScan.nextLine();
            System.out.println(command);
}Thats the code I have so far. I have an input file called "calculator.txt" which I made in notepad then copy/pasted into the same folder that this Calculator.java file is located. The build fails and sends this error:
unreported exception java.io.FileNotFoundException; must be caught or declared to be thrown
What am I doing wrong that it cant read the file?

Answer 1

"Exceptions" are written about and described in any Java book and they all contain plenty of example.
Your code shows no attempt whatsoever to handle an Exception. So the original answer assumed you didnt' know what an Exception was and gave you a resource to read.
It you would spend the time reading your text or the tutorial given instead of wasting time with these ridiculous comments you would have had your answer by now.
We don't have time to write a personal explanation about what an Exception is. We would only be duplicating what is in the book and tutorial.
On the other hand if your code acutally contained some code that resembled an attempt to catch an Exception, then you might have been given more specific help. If you don't understand that concept then you will have trouble getting answers in the forum.
Did you even search the forum to see if any other posting had a question about that Exception?
