Our guide covers everything from the basics to advanced topics. Whether you&#39;re just starting or have programming experience, we&#39;ve got you covered. Kotlin is a popular language for building Android apps. This Kotlin programming language tutorial includes lessons on its features like classes, objects, inheritance, and more.<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<h2 id=\"what-is-kotlin-programming-language\" style=\"line-height:1.38; margin-top:24px; margin-bottom:8px\">\n<span style=\"font-size:16pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">What is Kotlin Programming Language?<\/span><\/span><\/span><\/span><\/span><\/span><\/h2>\n<p style=\"line-height:1.38\">\n<span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">Kotlin is a versatile programming language used on different devices and systems. It can turn into code for computers that run Java, websites, and even standalone programs. Kotlin also makes it easy to use code from different platforms together, which helps build complex projects. In addition, you will learn Kotlin for Android in detail in this Kotlin programming language guide.<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<p>&nbsp;<\/p>\n<p style=\"line-height:1.38\"><span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">Kotlin was created by looking at other languages like Java, Scala, C#, and Groovy. The primary goal of Kotlin is to be practical and helpful for everyday programming. In other words, it has features and tools that make it easy to get things done. The designers of Kotlin make decisions based on what will be most useful for people who use it.&nbsp;<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<p>&nbsp;<\/p>\n<p style=\"line-height:1.38\"><span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">Kotlin is designed to prevent errors caused by missing values (called &#39;null&#39;). It can tell the difference between values that can be empty and those that always have something in them. As a result, this helps keep your code from crashing. Kotlin also has features that make it easier to work with other programming languages and write code more efficiently.<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<h3 id=\"history-of-kotlin-programming-language\" style=\"line-height:1.38; margin-top:21px; margin-bottom:5px\">\n<span style=\"font-size:13.999999999999998pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#434343\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">History of Kotlin Programming Language&nbsp;<\/span><\/span><\/span><\/span><\/span><\/span><\/h3>\n<p style=\"line-height:1.38\">\n<span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">After understanding the programming language of Kotlin, we will move ahead towards the history under this Kotlin basics tutorial. <\/span><\/span><\/span><\/span><\/span><\/span><br \/>\n&nbsp;<\/p>\n<p style=\"line-height:1.38\"><span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">The name &#39;Kotlin&#39; comes from an island in Russia. The people who created Kotlin decided to name it after an island, just like the programming language &#39;Java&#39; was named after an island. In addition, they wanted to give the language a unique and memorable name. In 2011, a company called JetBrains started working on a new programming language called Kotlin. They wanted a language that was better than the others they had tried but without the slow speed of another language called Scala. Kotlin programming language was designed to be as fast as Java and was made available to everyone in 2012.<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<p>&nbsp;<\/p>\n<p style=\"line-height:1.38\"><span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">JetBrains hoped that Kotlin would help them sell their software. They started working on Kotlin in 2010 and released the first stable version in 2016. In 2017, Google announced that it would support Kotlin for building Android apps. Later that year, Kotlin added a feature that lets you use the same code for both computers and websites.<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<h3 id=\"syntax-of-kotlin-programming-language\" style=\"line-height:1.38; margin-top:21px; margin-bottom:5px\">\n<span style=\"font-size:13.999999999999998pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#434343\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">Syntax of Kotlin Programming Language&nbsp;<\/span><\/span><\/span><\/span><\/span><\/span><\/h3>\n<p style=\"line-height:1.38\">\n<span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">Here, we will use the Hello World Code to discuss the syntax that will assist in developing Android apps with Kotlin.&nbsp;<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<p>&nbsp;<\/p>\n<p style=\"line-height:1.38\"><span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:italic\"><span style=\"text-decoration:none\">fun main() {<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"line-height:1.38\"><span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:italic\"><span style=\"text-decoration:none\">&nbsp;&nbsp;println(&quot;Hello World&quot;)<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"line-height:1.38\"><span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:italic\"><span style=\"text-decoration:none\">}<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<p>&nbsp;<\/p>\n<p style=\"line-height:1.38\"><span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">In Kotlin, you use the word &#39;fun&#39; to start a function. A function is like a mini-program that does a specific job. The &#39;main&#39; function is special because it&#39;s the first thing your program does. Any code inside the curly brackets of &#39;main&#39; will be run. For example, the &#39;println&#39; function is inside &#39;main&#39; and it prints text to the screen. In this case, it prints &#39;Hello World.&#39;&nbsp;<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<p>&nbsp;<\/p>\n<p style=\"line-height:1.38\"><span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">Before Kotlin version 1.3, you had to include &#39;args&#39; in the &#39;main&#39; function. However, this &#39;args&#39; was used for special information that the program might need.<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<h3 id=\"kotlin-uses\" style=\"line-height:1.38; margin-top:21px; margin-bottom:5px\">\n<span style=\"font-size:13.999999999999998pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#434343\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">Kotlin Uses<\/span><\/span><\/span><\/span><\/span><\/span><\/h3>\n<p style=\"line-height:1.38\">\n<span style=\"font-size:11pt; font-variant:normal; white-space:pre-wrap\"><span style=\"font-family:Arial,sans-serif\"><span style=\"color:#000000\"><span style=\"font-weight:400\"><span style=\"font-style:normal\"><span style=\"text-decoration:none\">Kotlin offers a modern, efficient, and safe programming language that combines the best aspects of Java while addressing its shortcomings.
