kotlin - Java ObjectOutputStream/ObjectInputStream

Question

I'm trying to implement Serializable interface for my class and I have a field in it that is of Enum class type. What should I call to write this field do byte stream?

class SingleEntry() : Serializable {
    // Category is an Enum class
    var category = Category.FOOD
    ....
    private fun writeObject(output: java.io.ObjectOutputStream) {
        output.writeObject(category)
    }
}

writeUTF(), writeObject() or some other is used for this purpose?
