How to fix Java nio NoSuchFileException wile reading a file

If you are using Java 7 java.nio classes to read a file, you may come across the NoSuchFileException if the file is not found. NoSuchFileException is a checked exception that was added to Java 7 and it extends FileSystemException that in turn extends IOException.


import java.nio.file.Files;
import java.nio.file.NoSuchFileException;
import java.nio.file.Paths;

public class Main {

    public static void main(String[] args)  {

        String fileName = "/Users/proj/src/main/sample.txt";
        try (Stream<String> linesStream = Files.lines(Paths.get(fileName))) {
        } catch (NoSuchFileException ex) {
            System.out.println("File not found:" + fileName);
        } catch (IOException ioe) {
Exception stack trace:
java.nio.file.NoSuchFileException: /Users/proj/src/main/sample.txt
