Rozpoczęcie tematu

Write a program that reads a list of words from the file words.txt and finds the count of vowels, consonants and other punctuation marks. Since English is a bit tricky, assume that a, e, i, o, u are vowels and all others are consonants. Punctuation marks are (!,.?). Do not count whitespace. Write the results in file count-chars.txt

Interesting taks! Here'e my solution:

import java.io.*;
import java.util.ArrayList;
import java.util.List;
 
public class Pr_03_CountCharacterTypes {
    public static void main(String[] args) {
 
        try (BufferedReader reader = new BufferedReader(new FileReader("resources/words.txt"));) {
 
            String line = reader.readLine();
 
            List<String> lineArray = new ArrayList<>();
            while (line != null) {
                lineArray.add(line);
                line = reader.readLine();
            }
            //CHECK IF THE ARRAY IS WORKING  System.out.println(lineArray);
            //            for (int i = 0; i < lineArray.size(); i++) {
            //                System.out.println(lineArray.get(i));
            //            }
 
            reader.close();
 
            try (BufferedWriter writer = new BufferedWriter(new FileWriter("resources/count-chars.txt"))) {
 
                int countVowels = 0;
                int countConsonants = 0;
                int countPunctuation = 0;
 
                String[] array = new String[lineArray.size()];
 
                for (int i = 0; i < lineArray.size(); i++) {
                    array[i] = lineArray.get(i);
                    String inspectLine = array[i];
 
                    for (int j = 0; j < inspectLine.length(); j++) {
                        switch (inspectLine.charAt(j)) {
                            case 'a':
                                countVowels += 1;
                                break;
                            case 'e':
                                countVowels += 1;
                                break;
                            case 'i':
                                countVowels += 1;
                                break;
                            case 'o':

                            default:

                writer.write("Vowels: " + countVowels);
