Sequence

Counting a letter

Core exercise

Write compterOccurrences(String texte, char lettre) that returns the number of times lettre appears in texte (case-sensitive).

A workshop goes here: you write and run code in it. It requires JavaScript.

Starting code

Exercices.java

public class Exercices {

    public static void main(String[] args) {
        System.out.println(compterOccurrences("anticonstitutionnellement", 't'));
    }

    public static int compterOccurrences(String texte, char lettre) {
        // TODO
        return 0;
    }
}

The core exercise is validated in the workshop, which requires JavaScript.

Hint 1

Walk through the string with charAt(i), from 0 to texte.length() - 1. Compare chars with ==: they are not objects.
