Kotlin Data Type FAQs
The Any type in Kotlin is the root of the type hierarchy and is the supertype of all non-nullable types. It can represent values of any non-nullable type. It is similar to Java's Object class.
null represents the absence of a value or a reference that does not point to any object.
Unit is used to represent functions that do not return any meaningful value, similar to void in Java. It is not the same as null.
You can use conversion functions like toByte(), toShort(), toInt(), toLong(), toFloat(), and toDouble() to convert between numeric types. You can also use casting for certain conversions.
A data class is a Kotlin feature that is used to automatically generate useful methods like equals(), hashCode(), and toString() for classes that are primarily used to store data. Data classes are concise and simplify working with structured data.
