What is Kotlin KTX extension?
KTX extensions add Kotlin language features, like coroutines, extension functions, lambdas, and named parameters to existing Android libraries. Support for multiplatform development. Kotlin Multiplatform allows development for not only Android but also iOS, backend, and web applications. Some Jetpack libraries are already multiplatform.
What is Kotlin type inference?
Kotlin’s approach to type inference gives you both conciseness and type-safety. In some languages, a reference type variable can be declared without providing an initial explicit value. In these cases, the variables usually contain a null value. Kotlin variables can't hold null values by default.
How does Kotlin implement conditional logic?
Kotlin features several mechanisms for implementing conditional logic. The most common of these is an if-else statement. If an expression wrapped in parentheses next to an if keyword evaluates to true, then code within that branch (i.e. the immediately-following code that is wrapped in curly braces) is executed.
Why do Android developers use Kotlin?
Over 50% of professional Android developers use Kotlin as their primary language, while only 30% use Java as their main language. 70% of developers whose primary language is Kotlin say that Kotlin makes them more productive. Using Kotlin for Android development, you can benefit from: Less code combined with greater readability.
Variable Declaration
Kotlin uses two different keywords to declare variables: val and var. 1. Use val for a variable whose value never changes. You can't reassign a valueto a variable that was declared using val. 2. Use varfor a variable whose value can change. In the example below, count is a variable of type Int that is assigned aninitial value of 10: Int is a type t
Conditionals
Kotlin features several mechanisms for implementing conditional logic. The mostcommon of these is an if-else statement. If an expression wrapped inparentheses next to an if keyword evaluates to true, then code withinthat branch (i.e. the immediately-following code that is wrapped in curlybraces) is executed. Otherwise, the code within the elsebranc
Functions
You can group one or more expressions into a function. Rather than repeatingthe same series of expressions each time that you need a result, you can wrapthe expressions in a function and call that function instead. To declare a function, use the funkeyword followed by the function name.Next, define the types of inputs that your function takes, if a
Classes
All of the types mentioned so far are built into the Kotlin programminglanguage. If you would like to add your own custom type, you can define a classusing the classkeyword, as shown in the following example: developer.android.com
Interoperability
One of Kotlin’s most important features is its fluid interoperability with Java.Because Kotlin code compiles down to JVM bytecode, your Kotlin code can calldirectly into Java code and vice-versa. This means that you can leverageexisting Java libraries directly from Kotlin. Furthermore, the majority ofAndroid APIs are written in Java, and you can ca
