KOTLIN – Programming Language<\/strong><\/h2>\n

 <\/p>\n

For Developing an Android application, android developers are using JAVA language but at present Android developers<\/a> also choose a new option Kotlin Programming language.<\/p>\n

Recommended Post:<\/strong><\/span>\u00a0How to Create Virtual Device in Android Studio<\/a><\/p>\n

What is Kotlin?<\/strong><\/h3>\n

Kotlin<\/strong> – Kotlin is a statically typed programming language that runs on the Java virtual machine and also can be compiled with JavaScript source code or use the LLVM compiler infrastructure. Its primary development is from a team of JetBrains programmers based in Saint Petersburg, Russia.<\/p>\n

While the syntax is not compatible with Java, Kotlin is designed to interoperate with Java code and is reliant on Java code from the existing Java Class Library, such as the collections framework.<\/p>\n

As of Android Studio 3.0 (Beta version), Kotlin is a fully supported programming language on Android and lets the user choose between targeting Java 6- or Java 8-compatible bytecode.<\/p>\n

Designed By<\/strong> – Kotlin Programming Language is designed by Jetbrains.<\/p>\n

Developer<\/strong> – JetBrains and open-source contributors<\/p>\n

Filename Extensions<\/strong> – is .kt, .kts<\/p>\n

Platform<\/strong> –\u00a0Outputs Java virtual machine bytecode and JavaScript source code<\/p>\n

Operating System<\/strong> – Any supporting JVM (Java Virtual Machine) or JavaScript interpreter<\/p>\n

License<\/strong> – Apache 2<\/p>\n

Why Kotlin?<\/strong><\/h3>\n
    \n
  1. Concise<\/li>\n
  2. Safe<\/li>\n
  3. Interoperable<\/li>\n
  4. Tool – Friendly<\/li>\n<\/ol>\n

    Explain it.<\/p>\n

      \n
    1. Concise<\/strong> –\u00a0Drastically reduce the amount of boilerplate code.<\/li>\n<\/ol>\n
      object MyObject\r\n{\r\n  val demoName: String = \u201cweblizar\u201d\r\n}\r\n<\/pre>\n
      2. Safe<\/strong> – Avoid entire classes of errors such as null pointer exceptions.<\/p>\n
      \/\/ NullPointerExceptions<\/strong>\r\nvar output: String\r\noutput = null   \/\/ Compilation error\r\n\r\n\/\/Kotlin protects you from mistakenly operating on nullable types<\/strong>\r\n\r\nval demo: String? = null    \/\/ Nullable type\r\nprintln(demo.length())      \/\/ Compilation error\r\n\r\n\/\/And if you check a type is right, the compiler will auto-cast it for you<\/strong>\r\n\r\nfun countSum(obj: Any) {\r\n    if (obj is Invoice)\r\n        obj.countSum()\r\n}\r\n<\/pre>\n
      3. Interoperable<\/strong> – Leverage existing libraries for the JVM, Android, and the browser.<\/p>\n
      \/\/Use any existing library on the JVM, as there\u2019s 100% compatibility, including SAM support.<\/strong>\r\nimport io.reactivex.Flowable\r\nimport io.reactivex.schedulers.Schedulers\r\n\r\nFlowable\r\n    .fromCallable {\r\n        Thread.sleep(1000) \/\/  imitate expensive computation\r\n        \"Done\"\r\n    }\r\n    .subscribeOn(Schedulers.io())\r\n    .observeOn(Schedulers.single())\r\n    .subscribe(::println, Throwable::printStackTrace)\r\n\r\n\/\/Target either the JVM or JavaScript. Write code in Kotlin and decide where you want to deploy to<\/strong>\r\n\r\nimport kotlin.browser.window\r\n\r\nfun onLoad() {\r\n    window.document.body!!.innerHTML += \"\r\nHello, Kotlin!\"\r\n}\r\n<\/pre>\n
      4. Tool-Friendly<\/strong> – Choose any Java IDE or build from the command line.<\/p>\n
      \/\/ A language needs tooling and at JetBrains, it's what we do best!\r\n\"\"\r\nRefrence From<\/a>\r\n<\/pre>\n
      What does it look like?<\/strong><\/h3>\n
      Concise, simple, and very easy to read (and write)<\/p>\n
      \"\"
      \nBasic Program in Kotlin<\/strong><\/p>\n
      Program Name – prg_1_HelloWorld.kt<\/p>\n
       \/\/Hello World Program in Kotlin\r\n<\/strong>\r\npackage weblizar.prg_1_HelloWorld\r\n\r\nfun main(args: Array) {\r\n  println(\"Hello, world!\")\r\n}\r\n<\/pre>\n
      Output<\/strong><\/p>\n

      How can Explore Kotlin Code with Kotlin-supported software?<\/strong><\/h3>\n
      Explore Kotlin Code using.<\/p>\n
      1.IntelliJ IDEA
      \n2. Android Studio
      \n3. Eclipse
      \n4. Compiler<\/p>\n
      In Brief –<\/strong><\/p>\n
      1. IntelliJ Idea – Bundled with Community Edition or IntelliJ IDEA Ultimate
      \n2. Android Studio – Bundled with Studio 3.0, plugin available for earlier versions
      \n3. Eclipse – Install the plugin from the Eclipse Marketplace
      \n4. Compiler – Use any editor and build from the command line.<\/p>\n","protected":false},"excerpt":{"rendered":"
