![]() In Kotlin, the three control statements used to evaluate conditional expressions are if, else, and when.Īn if statement allows you to specify code that should run if a conditional expression evaluates to true, whereas when allows you to specify multiple code branches to run depending on the actual value of a conditional expression. The most common way of achieving this is through the use of conditional expressions inside the loop.Ī conditional expression is one that evaluates to either true or false. When an iteration achieves its purpose - such as finding a given item in a list - it has to be terminated. Technically, you can iterate over anything in a for loop as long as it provides an iterator - like strings, arrays, ranges, and so on. Whatever the case, the for loop allows you to iterate over the collection and sequentially access each individual value in the collection. ![]() For example, maybe you want to find a particular item in a list, or you want to multiply each number in an array by two, or you want to get a subset of a string. Oftentimes, you might want to iterate over their values for various reasons. Some examples of these Kotlin data structures include strings, arrays, ranges, and maps. In Kotlin, there are several data structures that could contain a sequence of values. Overview of conditions and loops in Kotlin
