What is Kotlin?
Kotlin was introduced in 2011 when Android development required a modern language to add to the qualities of Java for advanced mobile app development. JetBrains created Kotlin, a contemporary statically typed programming language that works with the Java Virtual Machine (JVM). It is renowned for having an expressive and succinct syntax that lowers boilerplate code and improves readability. Null safety, extension functions, and coroutines are just a few of the sophisticated features that Kotlin provides to make basic programming jobs easier and increase developer productivity. Because of its compatibility with Java, it can be easily integrated with pre-existing Java codebases, which makes it a popular option for developing Android apps and other JVM-based applications. Kotlin is an attractive substitute for conventional languages like Java because of its contemporary features and user-friendliness.
Kotlin App Development Architecture
Kotlin Key Features:
- Java Interoperability: Kotlin enables you to use existing Java skills and knowledge and helps developers continue writing Android apps using their current programming language.
- Nullable Types: There is no need for "null" or "nil" in Kotlin, and it controls errors caused by absent types and parameters.
- Properties With Getters and Setters Created Automatically: Kotlin has properties that have getters and setters automatically generated. This makes coding easier for developers to code and read the Android app more quickly.
- Null Safety: It comes with null safety that controls errors usually caused by absent types or parameters that are not initialized correctly.
- Concise Syntax: No excessive tokens or keywords are required, and this Kotlin feature helps developers simplify the code.
Pros of Kotlin
Kotlin is quicker to write and takes less code to develop an app and thus it's a favorite of developers. This also means there are many fewer errors and bugs. Hire kotlin developers to leverage the capability for custom mobile app development.
- Kotlin allows writing less code.
- Kotlin aids in the building of clean APIs.
- It solves developer challenges.
- Kotlin is fully compatible with Java.
- It imposes no runtime overhead.
- Kotlin suits multi-platform development.
- Java libraries and frameworks can be used in Kotlin.
- Kotlin lets you use null, significantly easing the pain point.

What is Java?
Java is a computing platform and one of the most popular programming languages released by Sun Microsystems in 1995. It has grown from modest starts to power a large share of the digital world, developing mobile applications on reliable platforms. With Java, organizations can have new, innovative, and digital services designed for the future.
The latest Java patches include meaningful development that enhances the Java app's stability, performance, and security. Installing the latest Java updates confirms that mobile app agency offering Java applications will continue to run with the most up-to-date version.
Java is known for its secure, fast, and reliable language, so it is widely used in laptops, data centers, game consoles, mobile devices, and more.
Java App Development Architecture
Java Key Features:
- Memory Automatically Taken Care Of Utilizing Java, developers don’t have to worry about allocating and deallocating memory in their code because it has automatic memory management.
- Uses Garbage Collector: It uses a garbage collector to automatically handle the memory in the code. So, Java makes it easy for businesses to focus on their Android projects rather than manually managing memory.
- Supports Multiple Platforms: Java supports multiple platforms, and thus, developers love to work on Java and then switch over to Kotlin for Android app development projects.
- Java is one of the easy-to-use programming languages.
- With Java, you have to write code once and run it on almost any platform.
- Java is platform-independent, where programs developed in one machine can be performed in another machine.
- Java is designed for building object-oriented applications.
- It is a multithreaded language with automatic memory management.
- Java is also known to create for the distributed environment of the Internet.
If you plan to develop a Java application, then benefit yourself with excellent Java development services from the best enterprise mobile app development company.
Pros of Java
- Java is easy to learn and understand.
- Java performs well for native as well as cross-platform applications.
- There are plenty of Java libraries for your app development support.
- Also, Java has a broad open-source ecosystem.
- Java apps are lighter and more compact, resulting in a faster app experience.
- It delivers a quicker build process, letting developers code more in less time.
- Thanks to the accelerated assembly with Gradle to assist huge projects and make it more accessible in Java.
Cons of Java
- Verbose Syntax
- Null Safety Issues
- Slower Development
- Legacy Code
- Limited Language Features
Kotlin vs Java: Comparison Between Both Android App Development Languages
- Static Members
Static members in Java are used primarily for memory management, where developers can apply Java static keywords with methods, variables, nested classes, and blocks. Unlike Java, in Kotlin, the companion object assembles static members of the class. In addition, an object declaration can be written with the companion keyword inside the class.
- Performance
Talking about Java, it is a mature language with outstanding performance. Whereas Kotlin performs more reasonably than Java for Android development due to its capability and properties, it is 100% interoperable with Java.
- Type System
Using Kotlin, you will get type interfaces, nullability support, and universal guards. There are many reference types relevant to the class’s basic concept with Java.
- Popularity
Kotlin is a newer language than Java, but it has grown fast and become one of the most popular choices for Android app development. Google backs it, and thus, it can gain more support and advancement as time goes on. But Java is more popular than Kotlin in the current situation.
- Cross-Platform Development
Kotlin language is capable of cross-compiling multiple run-on platforms, while its use of bytecode limits Java. With Java, you can only be compiled for a single platform at once.
- Platform Compatibility
Kotlin supports JavaScript and bytecode along with native code compilation. On the other hand, Java language assembles bytecode for JVM and JS using Rhino and Nashorn JS Engines.
- Mature Libraries
When it comes to Java, has a vast collection of frameworks and tools for Android app development. Kotlin is starting to hook up with the opening of newer libraries such as KTX and Coroutines.
- Scalability
Unlike Kotlin, Java is not very scalable, and thus, the mobile application can sometimes get bloated, which can affect app performance.
Kotlin comes with stronger scalability and emphasis on its design, which improves the performance of an app by reducing bloat.
- Top Apps Developed Using Kotlin and Java
Some of the top apps built using Kotlin language are:
- Uber
- Airbnb
- Tinder
- Netflix
Some of the top apps built using Java language are:
- Cash App
- Spotify
- Community Support
Kotlin is a relatively new language in the market. So, the community of Kotlin is small compared to Java. So, there are more professional developers and a community of Java with experience in consulting exclusive Android applications.
Kotlin works best for specific applications and has led to many businesses' preferred choices in recent years.
Java vs Kotlin: Which is Better for Android App Development?
Both languages are fantastic and offer a range of benefits that would make them excellent choices to use in developing leading mobile applications.
Both languages are excellent and have their benefits. Hire Kotlin developers for scalable and feature-driven app development.
And if you are looking for an open-source project with more flexibility for third-party libraries, Java is the right option for business app development.
