The set() method takes 2 parameters: the index of the element and the value to be inserted. Guy Pierre de Coetnempren, count of 15-759c. Then we sorted this map by changing it to a list and with the help of. We inserted couple of values to this map and printed its key-values using a forEach. Here, we have created one hashMap with String as key and Int as the value. The get() method takes a single parameter-the index of the element and returns the value of the item at that index. KERSAINT, ARMAND GUY Simon de Costnempren, count of 15-759a. Method 1: sort a map by values by converting it to a list: Convert the map to a list. The get() and set() functions are said to be member functions. Therefore, we can access the data of a class object via its member functions. Now, let’s see how to access and modify them.Īs you know, an array in Kotlin is basically a class. For example, a range, array, string, etc. The for loop in Kotlin can be used to iterate through anything that provides an iterator. In Kotlin, the for loop works like the forEach in C. So far, we have seen how to create and initialize an array in Kotlin. Generally, the for loop is used to iterate through the given block of code for the specified number of times. Other factory methods available for creating arrays: These classes do not extend the Array class however, they implement the same methods and properties.įor example, the factory method to create an integer array is: The for-each construct is also applicable to arrays, where it hides the index.
