The topic of the discussion in this blog is between two programming languages, <strong>Kotlin or Java<\/strong>, and which of them is superior over the other. Before we go into which is superior or better than the other, it&#8217;s important to give you a quick rundown of their origin stories and history. So let\u2019s get into it.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Java was created by Sun Microsystems in the 90s. Ever since then, it has been the go-to programming language for app developers. On the other hand, Kotlin is a rather recent addition. It was first released to the public back in 2011 by a firm named JetBrains. Ever since then, it has been steadily gaining popularity as well as the endorsement of various different developers.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Despite the fact that both languages are created to run on the JVM, there are a few key distinctions that can make it or break it for a developer or <\/span><a href=\"https:\/\/trangotech.com\/mobile\/android-app-development\/\" rel=\"dofollow\"><span style=\"font-weight: 400;\">Android app development company<\/span><\/a><span style=\"font-weight: 400;\">, distinctions we\u2019ll be covering in this Java vs Kotlin blog.

What does WORA mean though? Well, the term &#8220;write only, run anywhere,&#8221; or &#8220;WORA&#8221; for short, refers to the fact that programmers only need to write Java code once and may then execute it on any hardware or operating system that has a JVM installed. Now, you ask, what is a JVM? The Java bytecode, which is a condensed and portable representation of Java source code, that is interpreted and executed by a software layer is known as the JVM, or Java Virtual Machine.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As a statically typed language, Java has a fixed data type for each variable and statement, which is verified at compile time. This facilitates error-free code compilation for Android developers and helps enhance the runtime performance of the application.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In addition, Java is also an object-oriented language (OOL), which means that it divides information and behavior into classes and objects that can communicate with one another via encapsulation, polymorphism, and inheritance.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Features of Java<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">We\u2019ve gone ahead and listed below all the features that come with using Java to code and create applications.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Java supports a variety of programming paradigms such as imperative, declarative, functional, and concurrent.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Java has a wide range of native data types, including primitives, arrays, strings, collections, and streams.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">It provides a wide range of utilities, including input and output, networking, database access, concurrency, security, and testing, through a standard library.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Java has a strong exception handling mechanism that enables you to gracefully manage mistakes and failures.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Enables you to develop more expressive and condensed code by providing robust support for generics, annotations, lambda expressions, and streams.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Has a strong concurrency model that enables the development of multithreaded programs that make use of several processors and cores.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Has a high-performance garbage collector that takes care of memory deallocation and allocation automatically.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Have access to a variety of frameworks and tools that can aid you in the creation of apps, including IDEs, testing tools, debugging tools, build tools, dependency management tools, web frameworks, and more.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">Drawbacks of Java<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Not everything that glitters is gold. Here are some downsides to utilizing Java that you can (potentially) encounter.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">It forces you to create A LOT of boilerplate code. Why? Because of its verbose syntax when doing routine activities.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Sadly Java does not support some contemporary features like null safety, extension functions, data classes, and coroutines that are accessible in other languages like Kotlin.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Its architecture has various restrictions and flaws, including the absence of multiple inheritance, the distinction between primitive and reference types, and the lack of operator overloading.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Its dynamic nature and dependence on the JVM has been reported to cause performance problems.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Because of its complicated governance mechanism and needs for backward compatibility, Java has a somewhat lengthy evolution process.<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Java-vs-Kotlin-What-is-Kotlin\"><\/span><span style=\"font-weight: 400;\">Java vs Kotlin<\/span><span style=\"font-weight: 400;\">: What is Kotlin?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Just like Java, Kotlin too is a programming language, but one that is made to be a superior substitute or alternative. It is an object-oriented, general-purpose language that can operate on the JVM, just like Java. But what distinguishes it as a superior choice? Well for starters, its support for other platforms including Android, iOS, JavaScript, and native code?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Despite being statically typed, Kotlin also offers type inference. This implies that developers are not required to explicitly identify the data type of each variable and expression. Based on the context and the value assigned to the variable, the compiler can determine the data type.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Although Kotlin enables functional programming, it is also an object-oriented language. What does that result in? The functions in Kotlin are treated as first-class constructs and can be passed as arguments, returned by functions, and stored in variables. Additionally, Kotlin has support for closures, lambdas, and higher-order functions, enabling programmers to be more compact and expressive when writing code.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Features of Kotlin<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">In this section, we\u2019ve discussed all the features that come with using Kotlin as your desired programming language.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Because of the clear and expressive syntax Kotlin boasts, it requires much less boilerplate code and makes programming much, much easier to read for programmers.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Kotlin has significant support for null safety, which implies that by recognizing nullable and non-nullable types, it avoids null pointer exceptions altogether.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Extension functions, a potent feature of it, lets you extend the functionality of existing classes without changing their source code or deriving from them.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Kotlin features a useful function called data classes that lets you make classes that solely contain data and automatically generates methods like equals, hashCode, toString, copy, etc.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Coroutines, a revolutionary feature of it, let you create asynchronous, non-blocking code in a sequential, synchronous manner.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Primitives, arrays, strings, collections, ranges, sequences, and other built-in data types are only a few examples of the extensive collection it has.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Various utilities, including input\/output, networking, database access, concurrency, serialization, reflection, etc., are provided via its extensive standard library.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">You can use any Java library or framework in Kotlin code and vice versa because it seamlessly interoperates with Java.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">It has a quick and intelligent compiler that carries out a number of optimizations and checks for faults and warnings during compilation.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">It has a thriving community that offers a range of frameworks and tools that can assist you with many parts of software development, including IDEs, testing tools, debugging tools, build tools, dependency management tools, web frameworks, microservices frameworks, etc.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">Drawbacks of Kotlin<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Now, let\u2019s go through the cons of using Kotlin as your programming language.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">For novice developers who are unfamiliar with its syntax and functionality, Kotlin has a relatively steep learning curve compared to Java.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Kotlin has some difficulty working with various Java frameworks and libraries that depend on reflection or annotations.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Because of the use of inline functions and lambdas, which produce additional bytecode and expand the executable file overall, Kotlin reportedly has (to some degree) speed difficulties.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Kotlin has a lengthy analysis and optimization procedure which slows down compilation speed. For example, Java is 15-20% faster in clean compilations without Gradle.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Kotlin has a less developed and stable ecosystem than Java, mostly because it is more recent.<\/span><\/li>\n<\/ul>\n<p><b>You Might Also Like:<\/b> <a href=\"https:\/\/trangotech.com\/blog\/react-native-vs-ionic\/\" rel=\"dofollow\"><i><span style=\"font-weight: 400;\">Ionic vs React Native: The Ultimate Performance Comparison<\/span><\/i><\/a><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why-compare-Java-and-Kotlin\"><\/span><span style=\"font-weight: 400;\">Why compare Java and Kotlin?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Despite the fact that they both have numerous similarities and differences, comparing them side by side can help developers better understand, assess, and evaluate their strengths and shortcomings.

Kotlin vs Java Syntax<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Starting of the Kotlin vs Java debate is \u201csyntax\u201d. Syntax refers to the rules and structure of a language that defines how to write and format the code, where one of the most noticeable differences between Java and Kotlin lies. Syntax can affect the readability, maintainability, and productivity of the code in question.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Java boasts a verbose and rigid syntax that requires you to write a lot of boilerplate code, even for common tasks. Let\u2019s put it into perspective, you need to declare the data type of every variable and expression, use semicolons to end every statement, use parentheses and curly braces to enclose every block of code, use keywords such as public, static, final, etc. to specify the modifiers and attributes of every class, method, and variable, etc.<\/span><\/p>\n<p><em><strong>public class Person {<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0private String name;<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0public Person(String name) {<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0this.name = name;<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0}<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0public String getName() {<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0return name;<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0}<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0public void setName(String name) {<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0this.name = name;<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0}<\/strong><\/em><\/p>\n<p><em><strong>}<\/strong><\/em><\/p>\n<p><span style=\"font-weight: 400;\">Kotlin on the other hand, has relatively concise and flexible syntax that enables you to write much less code to achieve the same level functionality. For example, you can omit the data type of variables and expressions if the compiler can infer it from the context, use line breaks instead of semicolons to separate statements, use indentation instead of curly braces to define blocks of code, use modifiers and attributes only when necessary or when they differ from the default values.<\/span><\/p>\n<p><em><strong>data class Person(val name: String)<\/strong><\/em><\/p>\n<p><span style=\"font-weight: 400;\">The succinct syntax of Kotlin enables developers to write cleaner and more maintainable codebases.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"2-Null-Safety\"><\/span><span style=\"font-weight: 400;\">2. Null Safety<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Null safety is another important difference between Java and Kotlin. It refers to the ability of a language to prevent or handle NPEs aka NullPointerExceptions (which are runtime errors that occur when you try to access or manipulate a variable or an object that has a null value).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Java currently does host a built-in mechanism to prevent or handle NPEs, as such, require you to manually check for null values before using any variable or object (that might be null). Why is this bad? When using Java and you make a mistake in your logic, you\u2019ll probably end up with an NPE that crashes your application entirely.<\/span><\/p>\n<p><em><strong>String name = null;<\/strong><\/em><\/p>\n<p><em><strong>\/\/ &#8230;<\/strong><\/em><\/p>\n<p><em><strong>int length = name.length(); \/\/ Throws NullPointerException<\/strong><\/em><\/p>\n<p><span style=\"font-weight: 400;\">Kotlin on the other hand has a built-in mechanism that helps prevent or handle NPEs. It distinguishes between nullable and non-nullable types by using a question mark (?) after the data type. A nullable type can hold a null value, while a non-nullable type cannot. The compiler checks for null values at compile time, enabling you to prevent using any variable or object that might be null without proper handling.<\/span><\/p>\n<p><strong><em>var name: String? = null<\/em><\/strong><\/p>\n<p><strong><em>\/\/ &#8230;<\/em><\/strong><\/p>\n<p><strong><em>val length = name?.length \/\/ No exception; length will be null if name is null<\/em><\/strong><\/p>\n<p><span style=\"font-weight: 400;\">Kotlin&#8217;s null safety forces developers to be explicit about null handling, reducing the overall risk of NPEs in the code.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"3-Type-Inference\"><\/span><span style=\"font-weight: 400;\">3. Type Inference<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Java requires developers to explicitly specify the data type of variables, which can result in more verbose code.<\/span><\/p>\n<p><em><strong>String name = &#8220;John&#8221;; \/\/ Type specified explicitly<\/strong><\/em><\/p>\n<p><span style=\"font-weight: 400;\">In contrast, Kotlin leverages the use of powerful type inference, which allows the compiler to determine the variable&#8217;s data type automatically.<\/span><\/p>\n<p><em><strong>val name = &#8220;John&#8221; \/\/ Type inferred automatically as String<\/strong><\/em><\/p>\n<p><span style=\"font-weight: 400;\">Why is this beneficial?

Extension Functions<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Another interesting difference between Java and Kotlin lies in extension functions. For those of you who don\u2019t know, extension functions are a feature that allows you to add new functionality to existing classes without modifying their source code or inheriting from them.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Java does not have support for extension functions. To use them, you have to either modify the source code of the class that you want to extend (which is not usually possible or at the very least desirable) or create a subclass that inherits from the class that you want to extend. This can introduce unnecessary complexities or overheads.<\/span><\/p>\n<p><em><strong>\/\/ Utility class example<\/strong><\/em><\/p>\n<p><em><strong>public class StringUtils {<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0public static String reverseString(String input) {<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\/\/ &#8230;<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0}<\/strong><\/em><\/p>\n<p><em><strong>}<\/strong><\/em><\/p>\n<p><em><strong>String reversed = StringUtils.reverseString(&#8220;Hello&#8221;);<\/strong><\/em><\/p>\n<p><span style=\"font-weight: 400;\">Unlike Java, Kotlin supports extension functions which helps improve code organization and readability by grouping related functions with the extended class. This can enable you to define an extension function by using the dot (.) notation after the class that you want to extend and then specifying the function signature and body. You can then call the extension function on any instance of the class that you extended as if it was a member function.<\/span><\/p>\n<p><em><strong>\/\/ Extension function example<\/strong><\/em><\/p>\n<p><em><strong>fun String.reverse(): String {<\/strong><\/em><\/p>\n<p><em><strong>\u00a0\u00a0\u00a0\u00a0\/\/ &#8230;<\/strong><\/em><\/p>\n<p><em><strong>}<\/strong><\/em><\/p>\n<p><em><strong>val reversed = &#8220;Hello&#8221;.reverse()<\/strong><\/em><\/p>\n<h2><span class=\"ez-toc-section\" id=\"5-Data-Classes\"><\/span><span style=\"font-weight: 400;\">5.
