While the first range will hold the list of multipliers corresponding to different rows, on the other hand, the second range will hold the result values. Further, we’ll need two ranges in our loop. We use let in Swift.Ĭonst val constants which are assigned at compile time.Let’s advance our understanding of looping with multiple variables by applying concepts of ranges and the zip operator to generate multiplication tables, where each row shows up in the format: factor x multiplier = resultĪs the factor will remain the same in all the rows, we’ll have to loop through two multiplier and result variables. Var number:float = 5.45 // Gives error as by default decimals are interpretted as double.

Var number = 5.45 // Interpreted as Double We can explictly do this by giving the type name Var text = 'hello' // Here Kotlin finds out text is of String type. Var for variable, which is mutable and can be re-assigned. Supports functional programming ( eg:Lambda functions) REPL : Similar to Swift REPL, Kotlin also have an REPL where in which we can try out expressions. Interoperable : Interoperable with Java and Android libs (In Kotlin, the type system distinguishes between references that can hold null and those that cannot.) also compiled a cheatsheet that covers all 5 parts of this series, which you can find here. Type interpretation is also present for some types. This is Part 4 of Kotlin for Interviews, a series where I go over Kotlin functions and code snippets that came up often during my Android interview prep. Safe: Exceptions are caught at compile time.

(Type of a variable is known at compile time.) Kotlin is a statically typed programming language from JetBrains. Now Kotlin is officially announced for Android, I thought of getting started and below is my learnings, as an iOS developer, I am writing a comparison also whereever required.
