Question

Write a program that reads a text file and prints on the console the sum of the ASCII symbols of each of its lines. Use BufferedReader in combination with FileReader.

Answer 1

Here is my solution:

import java.io.*;

public class Pr_01_SumLines {
    public static void main(String[] args) throws IOException {
        File lines = new File("resources/lines.txt");
        BufferedReader reader = new BufferedReader(new FileReader(lines));

        String line = reader.readLine();

        while (line != null) {
            int symbolsTotalCount = 0;
            for (int i = 0; i < line.length(); i++) {
                symbolsTotalCount += line.charAt(i);
            }
            System.out.println(symbolsTotalCount);
            line = reader.readLine();
        }
        reader.close();
    }
}

 

Answer 2

Here's mine - wiht try-catch block - and particular output on FileNotFoundException and IOException exceptions:

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.Locale;
 
public class SumLines {
 
    public static void main(String[] args) {
        Locale.setDefault(new Locale("en", "EN"));
 
        try (BufferedReader reader = new BufferedReader(new FileReader("resources/lines.txt"))) {
            String line = reader.readLine();
 
            while (line != null) {
                int symbolTotalCount = 0;
                for (int i = 0; i < line.length(); i++) {
                    symbolTotalCount += line.charAt(i);
                }
                System.out.println(symbolTotalCount);
 
                line = reader.readLine();
            }
 
            reader.close();
        } catch (FileNotFoundException fileNotFoundEx) {
            System.out.print("File not found.");
        } catch (IOException inputOutputEx) {
            System.out.print("Invalid file.");
        }
    }
}
