Count the occurrences of a letter in a string

Question

I am trying to write a for loop in Java that will count the occurrences of a letter in a string. The user will enter the letter to count and the string in which to search. This

Answer 1

1. You need to know the char you wanna search. You can use char charToSearch = letter.toCharArray()[0];
2. Define a variable, such as count to count the occurrences of a letter in a given string.
3. Loop the string and compare each char, if the char is equal to the char to search, then count++;

Example--->

int count = 0;
char charToSearch = letter.toCharArray()[0];
for (int i = 0; i < sentence.length(); i++) {
    if (sentence.charAt(i) ==  charToSearch) {
        count++;
    }
}

System.out.printf("Occurrences of a %s in %s is %d", letter, sentence, count);
