Declare a Constant Map Usingmap[int]stringin Go Although direct constant maps are not feasible in Go due to map properties requiring runtime allocation, you can create a variable initialized once and treat it as a constant map throughout the program. ...
In Kotlin, it appears the idiom is to use the built-in factory methods like mapOf and arrayOf when possible. 3. Use type inference judiciously; declare explicit types for clarity and safety (to make sure you and the compiler are on the same page). Regarding type-safety and making sure...
The scope function refers to the Student object asitin the output. Without using the scope function, we would have had to declare a new variable and initialize it with the Student object’s value to access it. Use thealsoScope Function in Kotlin ...
Kotlin will contain many features in the language of programming. It will allow us to declare multiple variables simultaneously; this technique is called the destructuring of kotlin.

We declare a member/variable for the meta layer as usual, and load a reference from the tile map. Note that we mark the layer as invisible since we don’t want to see these objects, they are for annotating what is collidable only. Next we add a new helper method that helps us ...

Compared to Java, you can notice the lack of semicolons, the lack of brackets on empty class (you can add some if you need to declare beans via @Bean annotation) and the use of runApplication top level function. runApplication<BlogApplication>(*args) is Kotlin idiomatic alternative to Spr...
fun <K, V> Map.Entry<K, V>.component2() = getValue() Data classesCopy heading link We frequently create classes that do nothing but hold data. As you know, Kotlin makes them as short as possible by providing primary constructors that can declare properties: ...
// In Kotlin , you can do as /* In First Activity, let in activity layout there is button which has id as button. Suppose I have to pass data as String type from one activity to another */ val btn = findViewById<Button>(R.id.button) btn.setOnClickListener { val intent = Inte...
