9.2 Generic methods — count greater than a threshold

Total: 0 / 3 pts

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

Task

Fill in countGreater so that it returns how many elements are strictly greater than threshold, using compareTo.

An element equal to the threshold is not counted. The program prints 2 and then 1.

Your solution

public class Main {

    public static <T extends Comparable<T>> int countGreater(T[] arr, T threshold) {
        // count elements strictly greater than threshold

    }

    public static void main(String[] args) {
        System.out.println(countGreater(new Integer[]{3, 9, 2, 7}, 5));
        System.out.println(countGreater(new Integer[]{5, 5, 6}, 5));
    }
}
