Question

I am running the following code to try and read from a text file. I am fairly new to java and have been practicing by trying to create projects for myself. The following code is slightly modified from what I originally found to try and read a text file but for some reason it catching the exception every time. The text file that it is trying to read from only says “hello world”. I assume it must not be finding the text file. I put it in the same folder as the source code and it appears in the source packages (I’m using netbeans btw). It probably just needs to be imported differently but I can’t find any further info on it. In case my code is relevant here it is below.

package stats.practice;

import java.io.*;
import java.util.Scanner;

public final class TextCompare {

    String NewString;

    public static void main() {
        try {
            BufferedReader in = new BufferedReader(new FileReader("hello.txt"));
            String str;
            while ((str = in.readLine()) != null) {
                System.out.println(str);
            }
            in.close();
        } catch (IOException e) {
        } 
        System.out.println("Error");
    }
}

Answer 1

First step, replace below code

catch (IOException e){}

with

catch ( IOException e) { e.printStackTrace(); }

and also replace

main()

with

main(String[] args)

This will tell you the exact reason. and then you have to solve the actual reason.

Now for Netbeans, the file hello.txt has to be in your Netbeans project. like

<project_dir>
    |
    -->hello.txt
    -->build
    -->src
