Mastering Kotlin Coroutines

Solution: Flow Processing

Explore how to process Kotlin flows by applying transformations like map, filter, and drop. Understand the practical use of SharedFlow and StateFlow to manage state and share data streams in coroutines. This lesson helps you gain hands-on experience manipulating and collecting flow data effectively.

We'll cover the following...

Solution

The solution to the challenge we just solved is as follows.

suspend fun main(){
    println("Output of Part A")
    flowOf(1, 3, 5, 9)
        .map { it * it * it}
        .collect { println(it) }

    println("Output of Part B")
    (1..100).asFlow()
       .filter { it % 5 == 0 }
       .filter { is_Odd(it) }
       .collect { println(it) }

    println("Output of Part C")
    ('A'..'Z').asFlow()
       .drop(15)
       .collect { print("$it ") }

}

fun is_Odd(num: Int): Boolean = num % 2 != 0
