#Intro

Kotlin is a new programming language for the JVM. It produces Java bytecode, supports Android and generates JavaScript. The latest version of the language is Kotlin M5.3

Kotlin project website is at kotlin.jetbrains.org.

All the codes here can be copied and run on Kotlin online editor.

Let's get started.

This is a quick guide to Kotlin programming language. The previous part of this guide is here

#Object Oriented

fun main(args : Array<String>) {
  class local (val x : Int)
  
  val y = local(10)
 println("${y.x}")

	<resources xmlns:tools="http://schemas.android.com/tools">

	<!-- Base application theme. -->
	<style name="AppTheme" parent="Theme.AppCompat.Light">
	<item name="actionBarStyle">@style/Custom.ActionBar</item>
	</style>

	<style name="Custom.ActionBar" parent="Widget.AppCompat.ActionBar">
	<item name="logo">@drawable/img_logo</item>
	<item name="displayOptions">useLogo\|showHome</item>

	final ImageView imageView = (ImageView) view.findViewById(R.id.image);

	final int shadowSize = getResources().getDimensionPixelSize(R.dimen.shadow_size);
	final int shadowColor = getResources().getColor(R.color.shadow_color);
	imageView.setImageDrawable(new RoundedAvatarDrawable(mBitmap, shadowSize, shadowColor));
	if (SDK_INT >= HONEYCOMB) {
	imageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
	}

	String id = "randomtext_" + number; //let's say number is 1
	int resourceId = getResources().getIdentifier(id, "id", getPackageName());
	// the above will be the same as "R.id.randomtext_1"
	TextView txtRandom = (TextView) findViewById(resourceId);

	var animate = ObjectAnimator.ofFloat(someLayout, "alpha", 0.5f)
	animate.duration = resources.getInteger(R.integer.anim_short).toLong()
	animate.start()

	// Use Gists to store code you would like to remember later on
	console.log(window); // log the "window" object to the console
