![]() ![]() Pass these values to ArrayList constructor to convert the map to list. Use map.keys and map.values to get the all keys and values. ![]() Next, adding few key value pairs to the map. First create the HashMap object with HashMap() constructor. This approach is the simple one and easy. Converting HashMap to List in Kotlin Using ArrayList Constructor Map implementations such as HashMap or TreeMap can be converted into an ArrayList or List object.ĭifferent ways to do this conversion. ![]() Take a look at Kotlin's code for defining HTML strings val n = """ ! doctype html html head meta charset="UTF-8"/ titleHello World/title /head body div id="container" H1Hello World/H1 pThis is a demo page./p /div /body / HTML "".In this tutorial, We will learn how to convert the Map to List in kotlin programming. In Java, int can be implicitly converted to long int e = 10 long f = e // implicit conversion duplicates code Copy the codeĪnd then Kotlin, sorry, doesn't support it Val E: Int = 10 val F: Long = e // implicitness not allowed val F: Long = e.T Long() // OK Copy code Copy the code Unsigned type (compatible with C Native)Īs of V1.3, Kotlin supports unsigned types String definition val d = 1234567890l // ok Copy the code Kotlin numeric type conversion In Kotlin, the compiler fails directly, forcing it to change to L Val c = 1234567890l // compile error. long d = 1234567890L // ok copy code Copy the code In Java, Long terminations with l can be compiled, but not recommended (lowercase L, which looks like the number 1). The value must be specified and cannot be changedĬompared with the Java int a = 2 final String b = "Hello Java" Copy the code Copy the code Var a = 2 val b = "Hello Kotlin" copy code Copy the code Confusing Long type tag Kotlin's variable declaration, somewhat similar to TypeScript, is a more modern form of modifier variable names: type = value, where the type declaration can be omitted. This section focuses on the built-in types and simple usage of Kotlin Declaration of variables Val b: String = "Hello Kotlin" copy code Copy the code ![]()
