public class MatchFlight {

public static void main(String[] args) {

List<Integer> nums = Arrays.asList(1,2,3,4,5,6,7);

boolean allPositive = nums.stream().allMatch(num->num>0);
System.out.println("allPositive: "+allPositive);

boolean anyEvenAvailable = nums.stream().anyMatch(num->num%2==0);

Output:
allPositive: true
anyEvenAvailable: true
noneNegative: true
