Answer 1

public class Main {
    public static void main(String[] args) {
        int[] array = new int[10];
        array[0] = 2;
        array[1] = 5;

        array[5] = 5;
        array[6] = 6;
        array[7] = 2;
        array[8] = 1;
        array[9] = 1;
        int count;
        int newSize = 0;
        for (int i = 0; i < array.length; i++) {
            count = 0;
            for (int j = 0; j < array.length; j++) {
                if (array[i] == array[j] && i != j) {
                    count++;
                }
            }
            if (count > 0) {
                System.out.println("The element " + array[i] + " the number of duplicates " + count);
            } else {
                newSize++;
            }
        }
        int[] tmp = new int[newSize];
        int k = 0;
        for (int i = 0; i < array.length; i++) {
            count = 0;
            for (int j = 0; j < array.length; j++) {
                if (array[i] == array[j] && i != j) {
                    count++;
                }
            }
            if (count == 0) {
                tmp[k++] = array[i];
            }
        }
        array = tmp;
