how to write a kotlin model class

[Murtaza Hussain]

model?? there are data classes in Kotlin which will generate toString and hashcode methods for you automatically and yeah getter and setters too.

[Ludovic Garcia]

Data classes also generate the really useful copy and equals functions.

private lateinit var customer_address_id: String
private lateinit var city: String
private lateinit var country_id: String
private lateinit var firstname: String
private lateinit var lastname: String
private lateinit var street: String
private lateinit var telephone: String

constructor()



fun getCustomer_address_id(): String? {
return customer_address_id
}

fun setCustomer_address_id(customer_address_id: String) {
this.customer_address_id = customer_address_id
}

fun getCity(): String? {
return city
}

fun setCity(city: String) {
this.city = city
}

fun getCountry_id(): String? {
return country_id
}

fun setCountry_id(country_id: String) {
this.country_id = country_id
}

fun getFirstname(): String? {
return firstname
}

fun setFirstname(firstname: String) {
this.firstname = firstname
}

fun getLastname(): String? {
return lastname
}

fun setLastname(lastname: String) {
this.lastname = lastname
}

fun getStreet(): String? {
return street
}

fun setStreet(street: String) {
this.street = street
}

fun getTelephone(): String? {
return telephone
}

fun setTelephone(telephone: String) {
this.telephone = telephone
}

Please, check data class docs

[gildor]

You need something like this:

data class User(var city: String, var telephone: String)

[gildor]

See
https://kotlinlang.org/docs/reference/data-classes.html

and consider use #getting-started
You question is not related to Android

[ghedeon]

@Azhar it's like forth time people suggest you #getting-started. IMHO, learning by try and fail, collecting random bits of information from slack threads is going to be extremely slow, You need something more systematic, with lessons and exercises. Any online Kotlin course for beginners will do (Coursera and such).
