![]() ![]() The following code will print all the integers between 0 and 100 that are divisible by 3 and 5. val numbers listOf(1, 2, 3) val map mapOf(1 to One, 2 to Two, 3 to Three). To do something useful with the iterator, we can use some of the other methods from the standard library e.g. The following code will create an infinite iterator over the integers 0, 1, 2, 3.: var i = 0 Kotlin flows are similar to Java streams, but with a focus on asynchronous programming. ![]() For infinite iterators, just never return null. To read an integer number from user entered in a console input in Kotlin, we can use readLine () function and String.toInt () method. In Part 1, I'll be going over the default Kotlin namespace.īoth the API docs and the source code for the stdlib are available on github.įirst up, the iterate method creates an iterator from a stateful function that returns either a value if it has more data or a null if not. In this series, I thought I'd look at some of the highlights of the Kotlin stdlib. suspend fun updateIntance(dbInstanceIdentifierVal: String, masterUserPasswordVal: String. ![]() Find the complete example and learn how to set up and run in the AWS Code Examples Repository. A few options: use TreeMap, which is the simplest of all, but it allows more types than just Int and String, and requires additional conversion boilerplate on the consumer side when accessing values. This is prerelease documentation for a feature in preview release.![]() Exploring the API docs and source code for a language's standard library is usually illuminating and Kotlin is no different. There is no union type in Kotlin, so you cant directly express this. ![]()
