public class Exercise30 {
public static void main(String[] args)
{
int[] array_nums = {50, 77, 12, 54, -11};
System.out.println("Original Array: "+Arrays.toString(array_nums));
System.out.println("Result: "+test(array_nums));
}
public static boolean test(int[] numbers) {
for (int number : numbers) {
if (number == 0 || number == -1) {
return false;
