public class CollectionDemo {
  public static void main(String[] args) {
    Integer[] numbers = { 8, 2, 6, 7, 0, 1, 4, 9, 5, 3 };
    int min = (int) Collections.min(Arrays.asList(numbers));
    int max = (int) Collections.max(Arrays.asList(numbers));
    System.out.println("Min number: " + min);
    System.out.println("Max number: " + max);
  }
}

Min number: 0
Max number: 9
