kotlin fun return multiple values
What is a generic function in Kotlin?
For more information on generic functions, see Generics. Kotlin supports a style of functional programming known as tail recursion. For some algorithms that would normally use loops, you can use a recursive function instead without the risk of stack overflow.
Why is Kotlin limit 5?
The Kotlin limit is five because it has defined five componentN extension functions on arrays and collections. Sometimes, it’s better to define a custom type with a meaningful name. This way, in addition to using the destructuring syntactic sugar, we can convey a particular meaning in the function declaration:
Does Kotlin support tuples?
2. No Tuples in Kotlin Some programming languages such as C# and Scala have first-class support for tuples. Therefore, we can easily assign tuples to variables, pass them to functions, or even return them from functions. On the other hand, Kotlin does not support creating arbitrary tuples, so we can’t return multiple values like:
How to return multiple values from a function in Kotlin?
One way to return multiple values from a function in Kotlin is by using data classes. Data classes are special classes that are designed to hold data and provide useful methods automatically. data class Result (val value1: Int, val value2: String) fun calculate (): Result { val value1 = 10 val value2 = "Hello" return Result (value1, value2) }
