public class Answer {
    public static void main(String[] args) {
        int[][] array = new int[12] [1];
        System.out.println("Enter twelve numbers: ");
        Scanner scanner = new Scanner(System.in);
        for (int i = 0; i < array.length; i++) {
            array[i][0] = scanner.nextInt();
        }
        System.out.print("Enter a number to search:");
        int matcher = scanner.nextInt();
        int ans = 0;
        for (int[] ints : array) {
            if (matcher == ints[0]) {
                ans++;
            }
        }
        System.out.println(" Occurrence(s) : " + ans);
    }
