File not found error in java, file is in my project folder?

Question

The file is in my project, and named correctly, I am quite new to JAVA. Any hints would be appreciated, TIA.

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class ExceptionsAndCarryOn {

    public static void main(String[] args) throws FileNotFoundException {
        // TODO Auto-generated method stub

        Scanner UserInput = new Scanner(new File("Numbers.txt"));
        System.out.println("Please enter the numbers: ");

        int [] numbers = new int [5];
        int i = 0;
        while(UserInput.hasNextInt()){
            numbers[i++] = UserInput.nextInt();
        }

        int sum = 0;
        for ( i = 0; i < numbers.length; i++)
            sum += numbers[i];
        System.out.println(sum);

        UserInput.close();

    }

}

@C.Roberts you told user user to type "Please enter the numbers: " but not taking the input. Not an error but you can modify it. — SachinSarawgi, Dec 02 '16 at 10:54
what do you mean by 'current folder'? besides java code in src folder? or at project root folder? — sidgate, Dec 02 '16 at 10:58
By *current folder* do you mean the src folder or the build/classes folder? — Ébe Isaac, Dec 02 '16 at 10:58
When you're using relative paths, you've to be careful of which directory is your current working directory. When you're telling the system to look just for 'Numbers.txt', it'll look for it in the current working directory. When you're running your project straight from the IDE, the current working directory is set to the project folder (the same place that contains your bin and src folders). That's where it's looking for numbers.txt. So if you put it in the src folder, you need to update the relative path accordingly. — Yash Capoor, Dec 02 '16 at 11:24

Put the file Numbers.txt in the project folder , parallel to the src folder. not inside the src folder.

That will solve your problem . Since you are not providing the fully qualified name (absolute path) . the JRE will assume that the file should be in the project folder from where your application is being run.

You can put the file in any folder and use fully qualified names like:

   Scanner UserInput = new Scanner(new File("D://Sunit//Numbers.txt"));

one of these can be the cause of the issue

file is in the current working directory
file has that specific name and extension
if you're using windows enable the "show extension for hidden files" property from the settings. otherwise it could happen that Numbers.txt.txt is the actual name

You stated that the file is in your project/src folder. That is where the source files are present, not executed.

When the .java files are compiled, the bytecodes (.class files) are stored in the build/classes directory. You may keep the Numbers.txt there, but it will be deleted once you give the clean and build option.

You have two alternatives:

Change the path in the code to "../../src/Numbers.txt"
Move the Numbers.txt anywhere and give the absolute path.
