Given this structure
record Mall(Collection<Shop> shops) {}
record Shop(Collection<Employee> employees) {}
record Employee(int age) {}
And this code
Shop firstShop = new Shop(List.of(new Employee(15), new Employee(17)));
Shop secondShop = new Shop(List.of(new Employee(12), new Employee(40)));
int result = new Mall(List.of(firstShop, secondShop))
.shops()
.stream()
.flatMap(shop -> shop.employees()
.stream()
.map(Employee::age))
.mapToInt(Integer::valueOf)
.max()
.orElseThrow();
What is the value of result?
