Join in Kotlin coroutines

  In Kotlin coroutines, the  join()  function is used to wait for the completion of multiple coroutines running concurrently. It allows you to ensure that all the launched coroutines finish their execution before proceeding further in the code. When you launch multiple coroutines using  launch ,  async , or other coroutine builders, you obtain references to these launched coroutines. You can store these references in variables and later use  join()  on each of these variables to wait for the corresponding coroutines to complete. import kotlinx.coroutines.* suspend fun doTaskA() { println(“Task A started”) delay(2000) // Simulate some asynchronous work for 2 seconds println(“Task A finished”) } suspend fun doTaskB() { println(“Task B started”) delay(3000) // Simulate some asynchronous work for 3 seconds println(“Task B finished”) } fun main() = runBlocking { val jobA = launch { doTaskA() } val jobB = launch { doTaskB() } println(“Launched both coroutine...
