Hope you all have like these handy features of kotlin which make development even easier. The negated counterpart of in Kotlin is which is used to compare if both the values are not equal to each other. It will only be true if both the objects or variables pointing to the same object. If we use 'Any', we can mix and match the data types, which means we can have. There should not be any mix and match between the data types inside a collection. When we define a collection with ' ', it should contain the object of only that type. Where writing this before accessing the member is optional but when using also than it’s mandatory to access member through it keyword. operator is used to compare the reference of two variable or object. In this article, we will demonstrate the difference between ' ' and ' Any ' keywords in Kotlin. One point to remember here is that apply makes it’s member available with this keyword whereas also makes them available with it keyword.

Well to handle that kind of scenario combination of apply and also works well. Kotlin Paradigm Multi-paradigm: object-oriented, functional, imperative, block structured, declarative, generic, reflective, concurrent Designed by JetBrains Developer JetBrains First appeared J11 years ago () Stable release 1.8. Next, let’s create a couple of Kotlin functions to address the usage of the is and is operators: fun isString(obj: Any): Boolean obj is String fun isNotString(obj: Any): Boolean obj is String. fun loadFragment(loadToBackStack:Boolean = false, load: FragmentTransaction.() -> Any) In Kotlin, we use the ‘is‘ operator to check if the given object is in a certain type. So let’s see how higher order function can help out . We can iterate over an array, collection, string, range, or anything which can be iterated with the help of a for loop.Load Fragment In case you want to load fragment than it’s important to commit the transaction and in case you forget it than studio do gives warning but there should be some better way to fix it rather than manually adding commit to your transactions. The for loop is used to iterate over any Kotlin object which can be iterated. The for loop in Kotlin is similar to forEach loop in Java. There is no traditional for loop in Kotlin unlike C, C++, Java etc., which will execute until a condition returns false. In this tutorial, we will discuss about for loop in Kotlin.
