Kotlin vs Java: Which Is Best for Developing Android Apps?
Meta’s Android repository is very large and reaches across our family of apps and technologies, including Facebook, Instagram, Messenger, Portal, and the Quest. Shifting away from Java, which we currently use for Android development, and over to Kotlin is not a trivial task. In recent years, Kotlin https://globalcloudteam.com/tech/kotlin/ has become a popular language for Android development. So it only makes sense that we would shift our Android development at Meta to Kotlin as we work to make our development workflows more efficient. Kotlin is a popular language for Android development and offers some key advantages over Java.
The growing community of Kotlin developers proves that when a developer learns Kotlin, one will never write on Java again. What are the popular programming languages to learn in 2023? Adding a good compiler has been one of Kotlin’s development team main goals when they created this programming language.
Inline Functions
To draw you an overall picture, let me give you an example. When choosing between the old but gold Honda Accord and Tesla Model S, what would https://globalcloudteam.com/ you select? Similarly, the answer for “Java vs. Kotlin-question” is clear to developers, but not to all C-levels and decision-makers.
The code is drowned out in type declarations, temporary classes, and factories, which distracts me from fixing the actual problem. For me, as for the Android developer, the answer is obvious. For you, as for a person without a background in coding, the choice between those languages might not be so easy. Kotlin, on the other hand, avoids NullPointerException at runtime.
Reusable State Management With RxJS, React, and Custom Libraries
It isn’t easy to access the new it enhancements in mobile development. It script helps to configure projects in Android Studio for auto-completion aids, and it helps to reduce compile-time error detection. It compiles the code to a bytecode which can be executed in the JVM. Thus, all the libraries and frameworks made in it transfer and run in a its project. Kotlin Application Deployment is faster to compile, lightweight, and prevents applications from increasing size.

Popular applications developed using the Kotlin language are Netflix, Uber, Tinder, Airbnb, and Pinterest. Similarly, well-known applications developed using Java are Twitter, Spotify, and LinkedIn. Kotlin allows developers to extend a class with new functionality via extension functions. These functions, available in other programming languages like C#, aren’t available in Java. Is an open-source and modern statically typed programming language used by over 60% of Android developers today.
Null Safety
Note that Kotlin’s standard library totally depends on the Java class library. The most important thing in Kotlin vs Java performance is that Kotlin is a functional programming language. Basically, Kotlin consists of many useful methods, which include higher-order functions, lambda expressions, operator overloading, lazy evaluation and much more. Functional Programming makes Kotlin much handier when it comes to collections.
For over two decades, Java was the most popular programming language for various devices. Since the beginning of mobile applications, developers have been using Java to build thousands of apps. However, Google announced in May 2019 that Kotlin is the preferred programming language for Android apps in Google Play Store. On the other hand, Kotlin is a relatively new programming language that has been gaining popularity in recent years. Both languages are used to build applications for the Java Virtual Machine , but they differ in terms of syntax, features, and performance.

Android developers enjoy the Kotlin compiler, making each Kotlin project way more efficient. Kotlin has classes with constructors, along with nested, inner, and anonymous inner classes, and it has interfaces like Java 8. To create a class instance, call the constructor just like a regular function.
- There are only a few Kotlin developers available in the market so finding an experienced mentor is quite tricky.
- Some of the popular apps built using this language are Trello, Twitter, and Netflix.
- If you want to follow along and learn some of the language’s features, there is a great browser-based Kotlin playground you can use.
- Overall, Kotlin is a programming language that can be seen as taking the best bits and fixing up the bad bits of Java.
- This has made it very useful for application developers through the years, especially for client-server web applications.
- Data types of the same kind convert to accommodate smaller data types into larger data types.
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. I think it is not fair to post something like this in r/java and not post it in r/kotlin as well. To avoid the verbose grammar normally needed for null testing, Kotlin introduces a safe call, written ?
Why I use Java
Interop library by the Room developers as another option to reuse existing code, but there’s still necessary migration work needed for each processor. However, a lot of our code is simply about passing values around. For example, a Litho class, which defines UI and its styling, stays about the same length regardless of whether it’s in Java or Kotlin.
The language is commonly used for developing Android apps too. Java is also a popular choice for scientific and numerical computing, as well as Big Data applications. Secondly, Java is a statically typed language, which means that variables must be declared before they can be used. This can help to prevent errors, as well as making the code easier to read and understand.
Cloud Platform
It does so by tracking the explicit casts and is-checks for immutable values. To handle lengthy operations in an Android app, Java lets you create multiple threads. But this makes the programming codebase bulkier, which could subsequently increase the chance of code errors.
