Total: 0 / 3 pts

Practice mode — check each part and get hints as you go.

Task

Fill in the generic method countOccurrences so that it returns how many elements equal target. It must work for any type.

Compare objects with equals, not ==. The program prints 2 and then 3.

Your solution

public class Main {

    public static <T> int countOccurrences(T[] arr, T target) {
        // count elements equal to target, using equals

    }

    public static void main(String[] args) {
        System.out.println(countOccurrences(new String[]{"Ada", "Sam", "Ada"}, "Ada"));
        System.out.println(countOccurrences(new Integer[]{1, 2, 2, 2}, 2));
    }
}
