有没有办法在java 8中使用Streams合并两个for循环？

Question

I have two lists in which one is of type String and the other is of some entity object. How to iterate through those two lists or compare it by using java 8

List<Admin> admin= new ArrayList<>();

for (Admin ah : subProducers) {
    for (String value : values) {
        if (ah.getFirstName().contains(value) || ah.getLastName().contains(value)) {
            admin.add(ah);
        }
    }
}

I am currently using the for loop to verify that condition, I don't find any better way to combine it using java 8 streams.

Something like an anyMatch with nested streams :

subProducers.stream()
            .filter(a -> values.stream()
                               .anyMatch(b -> a.getFirstName().contains(b)
                                           || a.getLastName().contains(b)))
            .collect(Collectors.toList())
