import java.util.Arrays;
import java.util.List;

public class MyClass {
    public static void main(String args[]) {
        int[] array = {3, 5, 7, 9, 1, 0};
        int valueToFind = 9;

        List<Integer> list = Arrays.stream(array).boxed().toList();
        
        if (list.contains(valueToFind)) {
            System.out.println("Found");
        } else {
            System.out.println("Not found");
        }
    }
}
