I have a JSON response like below image, and I have made a serializable class named as Project

In the image, I have two objects (emergency_contact, and secondary_owner)inside my an array of one object. I'm trying to figure out whether what to do in order to define the object, since I want that details to be present inside my constructor.

I have done this so far :

public class Project implements Serializable {

   public int id;

   public String name;

   public String additional_information;

   //Now what to do Emergency contact



   public Project(int id, String name, String additional_information){



   }

}

What I have thought of doing this, public EmergencyContact emergency = new EmergencyContact(param1, param2)

And make a new class named as EmergencyContact, and do a getter and setter for the params. But after doing this, I'm still confused, how would I define it my constructor?

I know I'm close, but I need some help on that. It would be highly appreciated. Thanks in advanced!

Sure. You need to have a:

public class EmergencyContact implements Serializable {



   public String name;

   public String number;



   public EmergencyContact(String name, String number){

     // assign fields 

   }

}

and one for the owner:

public class EmergencyOwner implements Serializable {



   public String name;

   public String number;



   public EmergencyOwner(String name, String number){

     // assign the fields

   }

}

then in your Project class you can add fields of these classes:

public class Project implements Serializable {

   public int id;

   public String name;

   public String additional_information;

   public EmergencyContact emergency_contact;

   public EmergencyOwner emergency_owner;



   public Project(int id, String name, String additional_information, EmergencyContact emergency_contact, EmergencyOwner emergency_owner){

     // assign the fields here as well

   }

}

that's it. If that's an answer to the question consider to delete this question as it is a duplicated on a 100% :)

As a note, to be correctly from the point of clean code parameters, the fields should be private in a class, and use setters / getters to set/retrieve values from/to those fields.

public class Project implements Serializable {

   private int id;

   private String name;

   private String additional_information;

   private EmergencyContact emergency_contact;

   private SecondaryOwner secondary_owner;



   public Project(int id, String name, String additional_information, EmergencyContact emergencyContact, SecondaryOwner secondaryOwner){

       this.id = id;

       this.name = name;

       this.additional_information = additional_information;

       this.emergency_contact = emergencyContact;

       this.secondary_owner = secondaryOwner;

   }

}

You will define the other two classes the same way. Now, you are probably confused about the constructor of EmergencyContact & SecondaryOwner classes.. You can device both default constructors (without parameters) and a custom one(with parameters to it, just as the one above). If you use the default constructor, make sure to set values to the fields in the object, as following :

EmergencyContact emergencyContact = new EmergencyContact();

emergencyContact.setName("the name");

emergencyContact.setNumber("a number");

then you can use this object in the constructor of Project class

I hope it was clear enough, for any other clarifications feel free to ask.

Happy coding <3
