Accessing a function in sealed class - devrath/KotlinAlchemy GitHub Wiki

  • Just like a regular class, we can also have functions in a sealed class, Here is the demo of it.
  • In the demo we even show-case that variable can be modified

MainActivity.kt

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val monkeyObj = Monkey()
        Log.d("Hello","<----START--->")
        monkeyObj.printColorOfAnimal()
        Log.d("Hello","Animal number: -> "+monkeyObj.animalNumber)
        monkeyObj.animalNumber++
        Log.d("Hello","Animal number: -> "+monkeyObj.animalNumber)
        Log.d("Hello","<----END--->")

    }

}

Animal.kt

sealed class Animal {
    init {
        Log.d("Hello","Initializing the animal class")
    }

    private val colorOfAnimal = "White"
    var animalNumber = 0

    fun printColorOfAnimal() {
        Log.d("Hello", "Animal color :-> $colorOfAnimal")
    }
}
object Camel : Animal()

class Monkey : Animal() {
     init {
         Log.d("Hello","Initializing the monkey class")
     }
}
