In this example, we will see how to stop the execution in the current loop and move back the compiler execution to the caller function. There are many ways to implement the desired behaviour in Rx. We can iterate through a JSONArray using a for loop: val booksJSONArray JSONArray. Kotlin Coroutines OkHttp interceptors RxJava Everything is a stream. Let’s look at some other ways which we can use instead. Hence, we can’t use the typical for-each pattern to iterate a JSONArray. Here, we execute the logic, summing only. The JSONArray class doesn’t implement the iterator operator. In Kotlin, the for loop is a control flow statement that allows you to iterate over a range, an array, a collection, or any other type of iterable object. Example: Return at labels :: directly to the caller The forEach function accepts as its parameter a code block that describes the effect for each number in the array. In this example, we will see how to do it. In Kotlin, we cannot explicitly use break and continue statements explicitly inside a forEach loop, but we can simulate the same action. In this article, we will see how break and continue work in Kotliln.īreak - This is a keyword that helps in terminating an iteration, once a given condition is met, while traversing through a collection.Ĭontinue - This keyword helps to continue the iteration once a condition is fulfilled. In Kotlin, we have three types of structural jump expressions: " break",
