Why doesn't it go further through the body of the loop?

Question

Java

There is a check function in which many checks are performed

static void checkAll()
    {

        while (true)
        {
            StudentOrder sO = readStudentOrder();
            if (sO == null)
            {
                break;
            }
            AnswerCityRegister cityAnswer = checkCityRegister(sO);
            if (!cityAnswer.answer) // if answer is  then keep going
            {
                continue; // if it's empty than go to the beginning of cycle
            }
            AnswerWedding weddingAnswer = checkWedding(sO);
            AnswerChildren childAnswer = checkChildren(sO);
            AnswerStudent studentAnswer = checkStudent(sO);

            sendMail(sO);
        }
    }

one of these checks is

static AnswerCityRegister checkCityRegister (StudentOrder sO)
    {
        CityRegisterValidator cityRegisterValidator = new CityRegisterValidator();
        cityRegisterValidator.hostName = "Host1";
        cityRegisterValidator.password = "Password1";
        AnswerCityRegister answer = cityRegisterValidator.checkCityRegister(sO);
        return answer;
    }

it uses the class declared as

public class AnswerCityRegister
{
   public boolean answer;
}

same class

public class CityRegisterValidator
{
    public String hostName;
    public int port;
    private String login;
    public String password;

    public AnswerCityRegister checkCityRegister (StudentOrder sO)
    {

        System.out.println("CityRegister is running : " + hostName + ", " + login + ", " + password + '.');

        AnswerCityRegister ans = new AnswerCityRegister();
        ans.answer = false;
        return ans;
    }
}

after executing the code, outputs "CityRegister is running : " + hostName + ", " + login + ", " + password + '.' but in theory he had to carry out other checks and reach the end, what is stopping him?

Answer 1

ans.answer = false;
return ans;
so answer is always false. The if(!answer) check is always true.
continue; // if it's empty than go to the beginning of cycle
says it all.
