Kotlin

Q1: What is a primary constructor in Kotlin? ☆☆

Answer: The primary constructor is part of the class header. Unlike Java, you don't need to declare a constructor in the body of the class. Here's an example:

mbobiosio

/**
 * ANY
 */
fun Any.toJson(): String = GsonInitializer.toJson(this)

/**
* String to Inches
**/
internal fun convertStringToInches(centimeters: String) : String =
(BigDecimal(centimeters.toDouble() * 0.393701).setScale(3, RpundingMode.HALF_EVEN)).toString()
