whats the point of OOP encapsulation?
hey guys. i was wondering if smb could help me out? im tired of reading countless articles that are copy pasted from each other so maybe a person and not a bot can explain stuff to me. in all the textbooks its said that "muh encapsulashun" is data hiding (whatever that means), using private fields, getters and setters. so now i have some questions: 1. who are we hiding the data from? lets say i have this: 
class Book {
    public String author;
    public int isbn;
}
class Book {
    public String author;
    public int isbn;
}
so? from who i need to hide the "data"? 2. lets say i want to hide "data", shouldnt i put it somewhere more safe? i.e. database, vault, etc? 3. whats the point of having private fields if u can just call the getter/setter? book.author is the same as book.getAuthor(). so why overcomplicate everything? thanks in advance. im trying to understand whats the point of this stuff.

how does open-closed principle really work?
hey guys. i have a question an id like to hear other opinions. lets say i have this.: 
public class MyService{
  //class fields, getters, setters
  public myServiceMethod(Car car){
    if(car.getColor()=="Red"){
      Print("Red car");
    }
    if(car.getColor()=="Green"){
        Print("Green car");
      }
    //do other business logic
  }
}
public class MyService{
  //class fields, getters, setters
  public myServiceMethod(Car car){
    if(car.getColor()=="Red"){
      Print("Red car");
    }
    if(car.getColor()=="Green"){
        Print("Green car");
      }
    //do other business logic
  }
}
it works fine. but then there comes a point when i need to check if the car is Yellow and Blue. then it means i have to add more if statements: 
public class MyService{
  //class fields, getters, setters
  public myServiceMethod(Car car){
    if(car.getColor()=="Red"){
      Print("Red car");
    }
    if(car.getColor()=="Green"){
        Print("Green car");
    }
    if(car.getColor()=="Yellow"){
        Print("Yellow car");
    }
    if(car.getColor()=="Blue"){
        Print("Blue car");
    }
    //do other business logic
  }
}
public class MyService{
  //class fields, getters, setters
  public myServiceMethod(Car car){
    if(car.getColor()=="Red"){
      Print("Red car");
    }
    if(car.getColor()=="Green"){
        Print("Green car");
    }
    if(car.getColor()=="Yellow"){
        Print("Yellow car");
    }
    if(car.getColor()=="Blue"){
        Print("Blue car");
    }
    //do other business logic
  }
}
now the questions arise: 1. is adding more if statements considered to be extension or modification? In my understanding its both. You modify code all the time. You changed variable name? Its modification. In Cambridge dictionary modification is described as a change to something. Refactoring is modification too. You cant write excellent code from the first try. 2. does the first and second pieces of code follow open-closed principle? why?

can request be validated before reaching the controller?
hey guys. im talking with a friend of mine and he mentioned that in php language you usually validate the data BEFORE it reaches the controller. i was wondering if this can be done in Java Spring app? as i understand this idea cant be done in Java Spring app. the controller in Spring app is the entry point to the application. and you cant really do much in Dispatcher servlet. what do you guys think? thanks in advance.

Soap request gives me 404 and "No endpoint mapping" even if everything is correct
Hello everyone. Its been almost a week and I still cant find an error and the reason why I am getting this kind of error. The thing is that my endpoint is correct, everything is set up fine. Earlier this endpoint had different name and everything worked fine. And now after changing the endpoint name everything just broke. Things I tried: asking chat gpt and gemini, asking for help on different discord servers, googling and browsing stackoverflow. The thing is that I cannot change the request body and I just need to use this request body. This is my Java code: https://pastecode.io/s/antg289v xsd and wsdl: https://pastecode.io/s/7142nmnr request body: https://pastecode.io/s/ng61346m console log: https://pastecode.io/s/1wg2oi2f Could somebody take a look and help me out? Huge thanks

how to return multiple objects in SOAP webservice?
hey guys. im developing SOAP webservice in java and i have a question. there are two operations checkId and createSale. and there are CheckIdRequestDTO, CheckIdResponseDTO, CreateSaleRequestDTO, CreateSaleResponseDTO. when validating checkId request and there are some errors, i set needed CheckIdResponseDTO fields to needed values and return the DTO and everything is fine. so my endpoint returns CheckIdResponseDTO in both cases: if its ok, or theres an error. But now im having trouble with createSale request. im validating CreateSaleRequestDTO, and if theres an error i dont have anything to return. I was thinking about constructing something like CreateSaleRequestErrorDTO. but then my endpoint cant return it. this is my endpoint so far: 
@Endpoint
@Validated

exception handling in SOAP webservices
hey guys. i have a question about SOAP webservice. i have this piece of code in my service layer: 
        Optional<Customer> customer=customerRepository.findById(Long.valueOf(perlasIdCheckRequestDTO.getUserId()));
        if (customer.isEmpty()) {
            log.info("PerlasService.checkId.NoCustomerException.CustomerId:{}.TransactionId:{}",perlasIdCheckRequestDTO.getUserId(),perlasIdCheckRequestDTO.getTransactionId());

            throw new NoCustomerException("No customer with customerId:"+perlasIdCheckRequestDTO.getUserId());
        }
        Optional<Customer> customer=customerRepository.findById(Long.valueOf(perlasIdCheckRequestDTO.getUserId()));
        if (customer.isEmpty()) {
            log.info("PerlasService.checkId.NoCustomerException.CustomerId:{}.TransactionId:{}",perlasIdCheckRequestDTO.getUserId(),perlasIdCheckRequestDTO.getTransactionId());

            throw new NoCustomerException("No customer with customerId:"+perlasIdCheckRequestDTO.getUserId());
        }
and i have this exception: 
@Getter
public class NoCustomerException extends RuntimeException {
    public NoCustomerException(String message) {
        super(message);
    }
}
@Getter
public class NoCustomerException extends RuntimeException {
    public NoCustomerException(String message) {
        super(message);
    }
}
and the exception is later handled by the RestResponseEntityExceptionHandler. so i have a couple of questions: 1. can i use the same exception? or do i need to create a duplicate one that will only be used for SOAP service? can i reuse the exception from my REST service? 2. how to handle the exceptions in SOAP webservices? i tried googling but honestly didnt understand a thing. can smb help me out? thx
