Why, when starting a test, it gives such an error and how to fix it

Question

Why it gives an NoSuchFileException error when accounting for the correct path set to Eclipse?.

This is the class Part1 used for testing and failing:

public class Part1 {
    private static String input = Part1
            .readFile("C:\\Users\\Влад\\eclipse-workspace\\Practice3\\src\\ua\\nure\\budiakov\\practice3\\part1.txt");
    private static final String ENCODING = "UTF-8";

    public static String readFile(String path) {
        String res = null;
        try {
            byte[] bytes = Files.readAllBytes(Paths.get(path));
            res = new String(bytes, ENCODING);
        } catch (IOException ex) {
            ex.printStackTrace();
        }
        return res;
    }

    public static String convert1(String input) {
        String[] text = input.split(System.lineSeparator());
        StringBuilder sb = new StringBuilder();
        for (int i = 1; i < text.length; i++) {
            String[] a = text[i].split(";");
            sb.append(a[0] + ": " + a[a.length - 1] + System.lineSeparator());
        }
        return sb.toString();
    }

    public static void main(String[] args) throws IOException {
        System.out.println(Part1.convert1(input) + System.lineSeparator());
    }

}
