With over two decades of experience in the industry, Daniel is a dynamic and strategic leader committed to driving growth and positive change. Whether you use Kotlin for front-end or back-end development depends on the type of development you choose to do. Web development, for one, requires web technologies like JavaScript, CSS, and HTML for front-end development and Kotlin can be utilized for back-end development. The average Kotlin developer in the United States makes $127,541 a year, according to ZipRecruiter salary data.
Null pointer exceptions are one of the most prevalent problems in Java projects. NullPointerException is an error generated in Java when the code tries to access an object with a null reference. To solve this in Java, programmers use preventive techniques like doing null checks before referencing an object’s methods or properties.
What is Kotlin Used For?
Kotlin is a general-purpose and open source programming language developed by JetBrains in the early 2010s. Kotlin is designed to fully interpolate with one of the most popular programming languages, Java. In 2019 Google announced Kotlin as a preferred language for Android mobile application development, which made it’s popularity grow significantly.
Additionally, when defining a subclass, properties in super-interfaces and super-classes can be overridden in the primary constructor. An Android developer might choose Java over Kotlin if they are new to Android software development. A new developer combing through these might find it easier to engage with them in Java rather than converting to Kotlin.
Our Kotlin App Development Services
Supporting code sharing between platforms, Kotlin makes developing apps across multiple Android operating systems, like Marshmallow and Nougat, more efficient. Kotlin’s open-source status allows developers to access its source code without purchasing a license or paying fees. This makes it easy for anyone to use and adapt the language as needed for their application requirements. In this article, we will discuss 12 reasons why you should use Kotlin for Android app development.
Because of this, migrating code from Java to Kotlin is a snap and developers wanting to make the transition do not need to rewrite their entire codebase from scratch. Since Google announced that the Kotlin programming language is now its preferred language for Android, many developers have moved to Kotlin for developing android applications. As a result, new job titles of Kotlin developers and Kotlin Android developers have emerged.
Mobile
The JVM itself is dependent on the operating system on which it is run, acting as a processor or “virtual” machine. Because it is aware of the specific instruction lengths of the operating system and other characteristics, the JVM is what makes Java itself platform-independent. It’s important to be aware of the fact that Java is a compiled language, which means that code is converted into machine-readable instructions before it is executed.
Kotlin may not be the first choice for cross-platform development, but this use of the language is gaining popularity among developers. With Kotlin Multiplatform, a software development kit meant for creating cross-platform apps, you can use one code base for both your Android and iOS projects. Ultimately, choosing between Java and Kotlin will depend on your specific needs and preferences. If your project requires high performance, stability, and a large codebase, backed up by plenty of framework options, libraries and tools, Java may be the better choice. If you are working on a software project or application that requires modern language features and support for functional programming, Kotlin is a great option.
Support
This is optional since Kotlin 1.3.[38] Perl, PHP, and Unix shell–style string interpolation is supported. Kotlin 1.3 added support for contracts,[35] which are stable for the standard library declarations, but still experimental for user-defined declarations. Contracts are inspired by Eiffel’s design by contract[36] programming paradigm.
Java has been around for decades and continues to evolve and grow in popularity, whereas Kotlin is relatively new, with a smaller community. Kotlin is often considered easier due to its concise syntax, modern features, and seamless interoperability with Java. However, the https://wizardsdev.com/en/vacancy/android-kotlin-developer/ ease of learning may vary depending on individual preferences and prior experience. It has a concise syntax, modern features, and is interoperable with Java, making it beginner-friendly. In Kotlin, everything (even the basic types like Int and Boolean) is an object.
Back-end web development
Using the example above, we can see how we don’t need to declare the variable type in the beginning of a HashMap. As an immutable variable a HashMap cannot become anything rather than a HashMap, but it can be used as usual to store key value pairs. A lot of back-end web development is done in Java, using frameworks like Spring. But, Kotlin made inroads into server-side web development since it was so much easier for developers to work with. As well as mobile and server-side applications, Kotlin is also being used for data science. It can be used for both server-side and client-side applications, both for web and Android.
- To add, Kotlin programming language can be used in the same projects alongside Java.
- No new subclasses can be added to it after the compilation of the module having the sealed class.
- Kotlin is a fully-featured language that supports object-oriented programming, functional programming, and metaprogramming.
- Type interface, smart casts, data classes, and properties help to achieve a high level of concision.
- We will also delve into advanced concepts such as coroutines, null safety, and functional programming in Kotlin.
- In fact, Kotlin gained popularity in 2019 when Google officially announced it as the preferred language for mobile app development in Android.
“While Microsoft does not share all of Oracle’s ambitions for Java, we agree that it is a very valuable tool for software developers.” – Bill Gates. There’s also the possibility of writing new code using Kotlin, and still having older code written in Java since the two languages are fully compatible. If you’re still undecided about Kotlin vs. Java for Android development, Revelo can help with decision-making.
