The above codes are the basic syntax for utilizing the kclass on both class and interface. We can declare the variable with specific data types, which can be called through the kclass type. How does kclass Work in Kotlin? Generally, the kotlin class works with many scenarios to implement ...
fun declareVar() { var a = 1 a = 2 println(a) println(a::class) println(a::class.java) var x = 5 // 自动推断出 `Int` 类型 x += 1 println("x = $x") } fun declareVal() { val b = "a" //b = "b" //编译器会报错: Val cannot be reassigned println(b) println(b::...
kotlinx.serialization provides a wasm-js flavor, so your projects with Kotlin/Wasm can have even more functionality. As usual, just add serialization dependencies to your build anddeclare wasmJs target. Please remember that Kotlin/Wasm is still experimental...

This is the main feature to consider that a language supports functional programming style, and Kotlin of course allows this. You can declare a function in a variable like this: val sum: (Int, Int) -> Int = { x, y -> x + y } See? This is a function that receives two integers...
Notice that you can also declare the parameter yourself explicitly. This is a better choice if you have nested lambda. The second convention applies only if a lambda is passed as argumentof the last parameterof a function. In such cases you can write the lambda outside the parentheses. If ...
In this example, we declare an array, fill it with data and then print the contents of the array to the console. val numbers = IntArray(5) We create an integer array which can store up to 5 integers. So we have an array of five elements, with indexes 0..4. ...
classC{privateval _elementList=mutableListOf<Element>()val elementList:List<Element>get()=_elementList} 选择好名称 类的名称通常是用来解释类是什么的名词或者名词短语:List、PersonReader。 方法的名称通常是动词或动词短语,说明该方法做什么:close、readPersons。修改对象或者返回一个新对象的名称也应遵循建议。
In the example, we declare aSimpleclass and later create an object from it. class Simple { private val name = "Simple" fun info() = "This is $name class" } A class in Kotlin is created with theclasskeyword. Inside our class, we have one property (member) and one function. ...
