code for kotlin:

import org.apache.fory.Fory
import org.apache.fory.ThreadSafeFory
import org.apache.fory.serializer.kotlin.KotlinSerializers

data class Person(val name: String, val id: Long, val github: String)
data class Point(val x : Int, val y : Int, val z : Int)

fun main(args: Array<String>) {
    // Note: following fory init code should be executed only once in a global scope instead
    // of initializing it everytime when serialization.
    val fory: ThreadSafeFory = Fory.builder().requireClassRegistration(true).buildThreadSafeFory()
    KotlinSerializers.registerSerializers(fory)
    fory.register(Person::class.java)
    fory.register(Point::class.java)

    val p = Person("Shawn Yang", 1, "https://github.com/chaokunyang")
    println(fory.deserialize(fory.serialize(p)))
    println(fory.deserialize(fory.serialize(Point(1, 2, 3))))
}

code for scala:

case class Person(name: String, id: Long, github: String)
case class Point(x : Int, y : Int, z : Int)

object ScalaExample {
  val fory: Fory = Fory.builder().withScalaOptimizationEnabled(true).build()
  // Register optimized fory serializers for scala
  ScalaSerializers.registerSerializers(fory)
  fory.register(classOf[Person])
  fory.register(classOf[Point])

  def main(args: Array[String]): Unit = {
    val p = Person("Shawn Yang", 1, "https://github.com/chaokunyang")
    println(fory.deserialize(fory.serialize(p)))
    println(fory.deserialize(fory.serialize(Point(1, 2, 3))))
  }
}
