Why the java stream break the outer loop if there is a match in the inner loop ! I mean it break from the outer loop

public class Employee {
    private long id;
    private Long nin;

}
public class Iban {
    private long id;
    private Long nin;
    
}

and I have the following data:

        Employee e1= new Employee();
        e1.setId(1);
        e1.setNin(111111l);
        
        Employee e2= new Employee();
        e2.setId(2);
        e2.setNin(222222l);
        
        Employee e3= new Employee();
        e3.setId(3);
        e3.setNin(333333l);
        
        List<Employee> employees = new ArrayList<>();
        employees.add(e1);
        employees.add(e2);
        employees.add(e3);

        Iban b1= new Iban();
        b1.setId(1);
        b1.setNin(111111l);
        Iban b3= new Iban();
        b3.setId(3);
        b3.setNin(333333l);
        
        List<Iban> ibans = new ArrayList<>();
        ibans.add(b1);
        ibans.add(b3);

i found that looping using java streams will print only one match while using normal loops will find two matches as below

// this will note iterate on all employees!
        for(Employee emp: employees){
            
            Optional<Iban> matchingContact = ibans.stream()
                    .findAny()
                    .filter(iban -> iban.getNin().equals(emp.getNin()));

            if (matchingContact.isPresent()) {
                System.out.println("***");
            }


        }

// while this  find two matches and will iterate over all employees
        for(Employee emp: employees){

            for(Iban ib: ibans){

                if(ib.getNin().equals(emp.getNin())){
                    System.out.println("***");
                    break;

                }

            }


        }

and it is expeted to find two matches !
