When I print for example alphabet.get(2).equals(allStrings.get(0)) (which is c and c) it returns false, but I am not sure why...
package com.codegym.task.task10.task1012;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.ArrayList;
/*
Number of letters
*/
public class Solution {
public static void main(String[] args) throws Exception {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
// Alphabet
String abc = "abcdefghijklmnopqrstuvwxyz";
char[] abcArray = abc.toCharArray();
ArrayList<Character> alphabet = new ArrayList<>();
for (char letter : abcArray) {
alphabet.add(letter);
}
// Read in strings
ArrayList<String> list = new ArrayList<>();
for (int i = 0; i < 10; i++) {
String s = reader.readLine();
list.add(s.toLowerCase());
}
ArrayList<String> allStrings = new ArrayList<>();
for (String s : list){
String[] separateLetters = s.split("");
for (int i = 0; i<separateLetters.length; i++){
allStrings.add(separateLetters[i]);
}
}
for (int i = 0; i<alphabet.size(); i++){
int count = 0;
for (int j = 0; j<allStrings.size(); j++){
if (alphabet.get(i).equals(allStrings.get(j))){
count++;
}
}
System.out.println(alphabet.get(i) + " " + count);
}
}
}
