String str = "RD Technical Learning";
List<Character> vcCheck = Arrays.asList('a', 'e', 'i', 'o', 'u');
char[] chars = str.toLowerCase().replaceAll("\\s", "").toCharArray(); // Need to convert string to lowercase and kill the space
for(char ch: chars){
-> val.equals(ch))){
System.out.println("vowels -> " + ch);
}else {
-> " + ch);
}
}

[technostacks]

// This is my approach
String input = "RD Technical Learning";
HashMap<Character, Integer> charCount = new HashMap<>();

char[] chars =
for (char ch : chars) {
if (!Character.isWhitespace(ch) && !Character.isSpaceChar(ch)) {
charCount.put(ch, charCount.getOrDefault(ch, 0) + 1);
}
}
for (char ch : charCount.keySet()) {
System.out.println("Character -> " + ch + " occurs ->" + charCount.get(ch));
}
