With the increase in demand for smartphones, the mobile app market revenue is also touching status and is expected to ascend to <a href=\"https:\/\/www.statista.com\/statistics\/269025\/worldwide-mobile-app-revenue-forecast\/\" target=\"_blank\" rel=\"noopener\">$935.2 billion<\/a> <strong>by 2023<\/strong>, clearly indicating the expanding demand of the mobile application.<\/p>\n<p>When it is time for you to make a choice between <strong>Java <\/strong>vs<strong> Kotlin<\/strong>, the top two official programming languages for your Android mobile application development, it is definitely a mind-boggling question to answer. With a deep study and understanding of the Android Development market analysis, we are posting down some significant verticals to make a differentiation among Java and Kotlin and make the procedure simpler for you.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Kotlin_Vs_Java\"><\/span>Kotlin Vs Java<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>Java<\/strong>, with 20 years of successful history, has a higher number of Java-based Apps in the Play Store. With its own set of advantages, the programming language <strong>Kotiln<\/strong>, introduced by <strong>JetBrains<\/strong>, has succeeded to mark its presence dominantly. Both of these powerful languages are considered the official languages for Android App Development by <strong>Google<\/strong>.<\/p>\n<p>Java has been the first choice of many companies for years, definitely for the obvious reasons like <strong>platform independence, robustness, cross-platform capabilities<\/strong>, etc, Kotlin, being a java-based language with even higher productivity, is also gaining so much popularity. Let\u2019s get out the disarray and look at the behavior of Java and Kotlin over the criteria crucial for an Application performance.<\/p>\n<h3>\u27a4 Interoperability<\/h3>\n<p>If you are already working on a programming language and are acquainted with all the technical nitty-gritty, switching to any other language might haunt you and hold you back from advancement. The Interoperability of the language proves to be extremely helpful in this case.<\/p>\n<p>Being compiled to bytecode and compatible with JVM just like Java, <strong>Kotlin is highly interoperable with Java<\/strong> and empowers you to use both the languages in unison that is using the Java code within Kotlin or vice-versa. To start with Kotlin, you need not start your project from scratch, rather you can use the modules in both the languages i.e. Kotlin or Java simultaneously, merely by installing the <strong>Kotlin plugin<\/strong>. Not only this, but you can also easily convert your Java program to Kotlin through the <strong>J2K converter<\/strong> included in the plugin. On the flip side, if we compare Java vs Kotlin, Java does not offer any such facility, requiring you to start from scratch itself, hence lags behind Kotlin in this context.<\/p>\n<h3>\u27a4 Code Brevity<\/h3>\n<p>Code Brevity, one of the very important factors considered in the structure of the program, making the code more comprehensible, cleaner, and is less prone to bugs thereby improving the quality of the code.<\/p>\n<p>Kotlin requires comparatively <strong>less number of LOC as compared to Java<\/strong>, making it more readable and understandable. For example, the \u2018Switch case\u2019 in Java has been converted to a fewer line code using \u2018when\u2019 in Kotlin.<\/p>\n<h4 style=\"text-align: center;\"><strong>Kotlin vs Java Code Conciseness<\/strong><\/h4>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter wp-image-19778 size-full\" src=\"https:\/\/www.aceinfoway.com\/blog\/wp-content\/uploads\/2020\/04\/1_2.jpg\" alt=\"Kotlin v\/s Java Code Conciseness\" width=\"836\" height=\"353\" \/><\/p>\n<h3>\u27a4 Easier Thread Managements through Coroutines<\/h3>\n<p>Android, being single-threaded, creates the main thread when the app is started, on which all the components run. The problem generally faced in the asynchronous approach is that it blocks the thread until the requested task is completed, freezing the UI of the app for that time.<\/p>\n<p><strong>Coroutines<\/strong>, an experimental feature introduced in Kotlin, has addressed this problem by <strong>replacing the thread blocking mechanism with the thread suspension<\/strong> which can be resumed later, making it extremely useful for the long-run task. Unlike Java, it does not create stacks of thread in order to execute the time taking tasks, rather it is stackless and works on a single thread, making it lightweight, easy to manage and more comprehensive.<\/p>\n<h3>\u27a4 Data Classes to reduce coding time<\/h3>\n<p>When you write a Java program, you create classes to hold data, constructors for object initialization, getter and setter functions to update and retrieve values for various declared fields, etc. which is a huge amount of code, you write for every program.<\/p>\n<p>Kotlin liberates you from this, through <a href=\"https:\/\/kotlinlang.org\/docs\/reference\/data-classes.html\" target=\"_blank\" rel=\"noopener\">Data class<\/a>, which provides you a lot of <strong>self-generated data<\/strong> such as equals()\/hashCode(), getter, setters, etc, enabling you to do the same task with a fewer Line Of Code. Data class not only reduces the <strong>boilerplate volume and the complexity but also saves a lot of time for the programmer<\/strong>. In Kotlin, if you want to create a code for a person\u2019s detail, you can simply do this in one line of code, rather than declaring the variables separately then applying getters and setters, and a lot more.<\/p>\n<h4 style=\"text-align: center;\"><strong>Kotlin vs Java Class Code<\/strong><\/h4>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter wp-image-19776 size-full\" src=\"https:\/\/www.aceinfoway.com\/blog\/wp-content\/uploads\/2020\/04\/1_1.jpg\" alt=\"Kotlin Vs Java Class Code\" width=\"836\" height=\"683\" \/><\/p>\n<h3>\u27a4 No Implicit Widening Conversions<\/h3>\n<p>Implicit Widening is the process of converting the data type implicitly, For Example: if an operand in the addition operation is of type Double, the other operand is automatically converted to Double type.<\/p>\n<p>Java supports the Implicit Widening Conversion, however, you need to do the conversion explicitly in case of Kotlin as it does not support the implicit conversions in order <strong>to prevent the loss of precision<\/strong>. A function in a Kotlin program, with a Float parameter, cannot be called on Int value, but only on Float value.<\/p>\n<h3>\u27a4 Null Safety<\/h3>\n<p>Null References, considered as a <a href=\"https:\/\/kotlinlang.org\/docs\/reference\/null-safety.html\" target=\"_blank\" rel=\"noopener\">billion-dollar mistake<\/a> by its creator <strong>Tony Hoare<\/strong>, is the most general problem faced by the Java Programmer. Null References generated <strong>NullPointerException<\/strong>, requiring you to invest your valuable time in spotting it in the huge codebase. Kotlin relieves you from this pain, providing you with the null type in the code which you can easily declare when required.<\/p>\n<h3>\u27a4 Popularity<\/h3>\n<p>Java has been one of the most preferred languages for quite a few years, in fact, many developers are still using it for their projects. The popularity of Java has seen a bit of downfall after the introduction of a similar yet highly advanced language that is Kotlin. Kotlin, due to its incredible functionalities and ease of use, has caught a lot of attention, making it the choice of around <strong>72.6 %<\/strong> of developers, according to Stackoverflow. On the contrary, Java managed to gain only <strong>53.4%<\/strong> of votes, clearly indicating the popularity of Kotlin.<\/p>\n<h4 style=\"text-align: center;\">Kotlin Vs Java Popularity: Most Loved Programming Languages 2019<\/h4>\n<div id=\"attachment_19770\" style=\"width: 831px\" class=\"wp-caption aligncenter\"><img aria-describedby=\"caption-attachment-19770\" decoding=\"async\" loading=\"lazy\" class=\"wp-image-19770 size-full\" src=\"https:\/\/www.aceinfoway.com\/blog\/wp-content\/uploads\/2020\/04\/rust-2.jpg\" alt=\"Kotlin Vs Java Popularity: Most Loved Programming Languages 2019\" width=\"821\" height=\"886\" \/><p id=\"caption-attachment-19770\" class=\"wp-caption-text\"><strong>Source:<\/strong> <a href=\"https:\/\/insights.stackoverflow.com\/survey\/2019#technology\" target=\"_blank\" rel=\"noopener\">https:\/\/insights.stackoverflow.com\/survey\/2019#technology<\/a><\/p><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The Boilerplate volume, Execution time, Code Conciseness, Ease of use, Understandability, Effectiveness, Error Handling, etc, are some major factors that contribute to the better performance of an application. Though Java has been the choice of many app developers since it was introduced, however, its complexities and drawbacks cannot be denied either.<\/p>\n<p>Kotlin, by removing all these complexities and introducing the improved as well as some advanced features, comes out a winner here. Kotlin is the future of Application Development and the best part about Kotlin is that it does not compel you for the immediate complete switch, rather allows you to head gradually.
