Klausimai apie JAVA

Gal kas patars del single responsability principo tokiame kode. Cia formuojamas path is user inputu. Kaip ir klase atlieka tai kas yra pavadinime, bet kiek skaiciau, klases kodas turi tilpti i ekrana, kitaip pazeidziamas SRP. Ka daryti su tokia klase, kaip ja perdaryti pagal SRP. Cia naudojami enum vietoje konstantu:

public class PathBuilder {

  public String getPath() {
       Messages.printMessage("\nEnter search keyword or phrase.");
       return String.format("%s%s%s%s", UrlPart.PATH_BEGINNING.getName(), UserInput.getSearchTerm(), UrlPart.SLUG_IMAGE_TYPE.getName(), getSlugWithSelectedFeatures());
   }

   private String getPhotoOrientationValue() {
       Messages.printMessage("Select photo orientation: [1] horizontal, [2] vertical. \nEnter number or press 0 to continue without selection:");
       int number = UserInput.getNumberInput();
       switch (number) {
           case 1:
               return UrlPart.SLUG_PHOTO_ORIENTATION.getName() + "horizontal";
