I’ve finally gotten around to learning Java and I’m trying to write an interpreter for an esolang. I looked up a few tutorials and wrote this code.

import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.Files;
import java.util.Scanner;
import java.util.List;
import java.util.ArrayList;

public class NDBall {
    public static Scanner scanner = new Scanner(System.in);

    public static void main(String args[]) {
        String input = scanner.nextLine();
        Path path = Paths.get(input);
        List<String> code = new ArrayList<String>();
        code = Files.readAllLines(path);
    }
}

However, the readAllLines function keeps giving me an error, and I don’t know why. It won’t tell me what the error is, and everything else seems fine. I’m doing it exactly as the tutorials I looked up told me.

Is there some mistake I made?

>Solution :

The below code will work for you. have hard coded the path so escape characters are taken care of:

import java.io.IOException;
import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

class Solution {

    public static Scanner scanner = new Scanner(System.in);

    public static void main(String args[]) {
        String input = scanner.nextLine();
        Path path = Paths.get("C:\\Users\\xyz\\Desktop\\imp.txt");
        List<String> code = new ArrayList<String>();
        try {
            code = Files.readAllLines(path, StandardCharsets.UTF_8);
            code.stream().forEach(System.out::println);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
