How to address a parameterized constructor

Question

There is such a class.

public class Passenger { Passenger(String name, String lastName, int year, String comfortLevel, double carryOn, double baggage, Boolean weapon, Boolean premiumCard){ name = name; // имя пассажира lastName = lastName; // фамилия year = year;// полных лет comfortLevel = comfortLevel;//класс билета carryOn = carryOn;//вес ручной клади baggage = baggage;//вес багажа weapon = weapon;// наличие оружия premiumCard = premiumCard;// наличие дисконтной карты } }

Next SellTicket class

 public class SellTicket { private double[] econom = {8.0, 4.0};// параметры класса вес багажа, ручной клади private double[] business = {12.0, 8.0}; private double[] comfort = {10.0, 6.0}; private int adult = 18;// возраст private int young = 16; private int baby = 5; void schekPass(Passenger p) {// проверяем в черном списке AviaSafe a = new AviaSafe(); a.checkPassenger(p); } void sheckYear(Passenger p){// смотрим возраст if(p.year >= adult){ } if(p.year >= young){ } if(p.year >= baby){ } } void checkComfort(Passenger p) {// if(p.comfortLevel == "comfort"){ } if(p.comfortLevel == "business"){ } if(p.comfortLevel == "econom"){ } } void sheckWeapon(Passenger p){// наличие оружия AviaSafe a = new AviaSafe(); a.checkWeapon(p); } void checkDiscountCard(Passenger p){ if(p.premiumCard){ //насчитываем авиамили и прочие плюшки } } }

I do not want to create a bunch of setters, getters. How to get access to the parameters of the designer?

If you do not want to write the boilerplate code , then use the lombok library

With it, it will be enough to add only one annotation @Data .

until came up with this option.

 public class Passenger { private String name; private String lastName; private int year; private String comfortLevel; private double carryOn; private double baggage; private Boolean weapon; private Boolean premiumCard; Passenger(String name,String lastName, int year, String comfortLevel, double carryOn, double baggage, Boolean weapon, Boolean premiumCard) { setName(name); setLastName(lastName); setYear(year); setComfortLevel(comfortLevel); setCarryOn(carryOn); setBaggage(baggage); setWeapon(weapon); setPremiumCard(premiumCard); } private void setName(String name){ this.name = name; } public String getName(){ return name; } private void setLastName(String name){ this.lastName = lastName; } public String getLastName(){ return lastName; } private void setYear(int year){ this.year = year; } public int getYear(){ return year; } private void setComfortLevel(String comfortLevel){ this.comfortLevel = comfortLevel; } public String getComfortLevel(){ return comfortLevel; } private void setCarryOn(double carryOn){ this.carryOn = carryOn; } public double getCarryOn(){ return carryOn; } private void setBaggage(double baggage){ this.baggage = baggage; } public double getBaggage(){ return baggage; } private void setWeapon(Boolean weapon){ this.weapon = weapon; } public Boolean getWeapon(){ return weapon; } private void setPremiumCard(Boolean premiumCard){ this.premiumCard = premiumCard; } public Boolean getPremiumCard(){ return premiumCard; }

}

Or you make public fields and communicate to them like this <object>. <FildName>.
