The key and value may be in the different pairs such as:
The key in the (K,V) stands for the key is unique and can only hold one value for each key. It also stores the data in the form of (K,V) key and Value pair. Here we discuss the introduction, syntax, and working of mapOf() function in Kotlin along with different examples and its code implementation.Kotlin Map is an interface and is the generic collection of all the elements. Like that mapOf() is one of the default methods under the map interface with util collection package which is used to store the user inputs on the key-value pairs and it is an immutable one so we can’t change it. In the kotlin language, we used many different packages which contain the classes with default methods. In the final example, we used the hash map concept additionally and we stored the employee details with same as mapOf() method.
Println("Your input Values are:" + news.values) Println("Your input Keys are:" + news.keys) Println("Thank you users your Entries list are: " + news.entries) Val news = mapOf("EmployeeID" to 456, "Employee PinCode" to 654332, "Employee Mobile" to 98654) Println("Thank you users your inputs are $k = $v") Println("Welcome to my domain its a third example regarding the kotlin mapOf() function") In the second example, we can validate the user inputs by using the conditional statements after registered on the mapOf() method. Println("Thank you users have a nice day please keep and spent time with our application") Examples of Kotlin mapOfĮxamples of Kotlin mapOf are given below: Example #1Įnum class First(val exampl: Boolean = true)") With an array we can fetch the value by using the index which has to be an integer data type and all indexes have to be the sequential orders. If we want to add the map entries to the original map by using default methods like put() method for to insert the user input entries on the memory.
The map interface used to creates the new map that contains the new entry values it does not mutate the original map. These methods are used to count the characters and it has calculated the sizes these entries are keys and values also some other default methods like contains and get the values from the mapOf() method which helps to iterate the values by using forEach() loop. Generally, the map is one of the collection and that can behold and pairs of objects and it is based on immutable maps that can be read-only format it also looks for the map size it has a number of pairs and it can be determined with the property size and the default method like count() and size() method. The mapOf() method helps to creates the read-only format and map value with the specified data contents on the list of pairs where the first index value is on the key format and the second index format is on the value. How does mapOf() function work in Kotlin?
