Hi,
Please assist me what cause the last condition to fail.
I tried it without using a hasmap, just printing it on line 46 instead of adding to the Map.
package com.codegym.task.task10.task1012;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.*;
/*
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());
}
HashMap<Character, Integer> map = new HashMap<>();
int count = 0;
String newString = null;
for (String s : list) {
newString += s;
}
char[] ch = newString.toCharArray();
for(int i=0; i<alphabet.size();i++){
for(int j =0; j<ch.length;j++){
if(alphabet.get(i)==ch[j]){
count++;
}
}
map.put(alphabet.get(i), count);
count=0;
}
for(Map.Entry<Character, Integer> c : map.entrySet()){
char e = c.getKey();
int val = c.getValue();
System.out.println(e+" "+val);
}
}//main method
}
