Question

Scanner Class couldnt find the file
I use NetBeansIDE, and the test.txt is in the folder path: D:\netbeans project works\ReadFile\src\readfile\test.txt

in the same folder the readfile.java exsist.
the code is as below.
It generates file not found.

package readfile;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Scanner;


public class ReadFile {

    public static void main(String[] args) throws IOException , FileNotFoundException 
    {  
        Scanner scanner = new Scanner(new File("test.txt"));  

        while (scanner.hasNextLine())  
            System.out.println(scanner.nextLine());  
    }  
}

output:-

run:
Exception in thread "main" java.io.FileNotFoundException: test.txt (The system cannot find the file specified)
    at java.io.FileInputStream.open(Native Method)
    at java.io.FileInputStream.<init>(FileInputStream.java:106)

Answer 1

Add the following before creating Scanner class:

System.out.println(new File("test.txt").getAbsolutePath());

It will show you where JVM expects to find the file and whether it is the folder you expect as well.

Also check file permissions. But most likely it is a problem with default JVM directory.
