The absolute reliability of Java as a programming language, Android was long in need of a modern language. Kotlin fulfilled that gap ever since it was announced as the official language for Android development. Kotlin was created specifically to replace Java, and it has been compared with Java in many regards.
For many developers, Java is the best programming language, it is everywhere and everyone praises it. However, the addition of Kotlin, this manifest confidence in Java is somewhat shaken. Kotlin also has been doing well in the field of Android app development. Google acknowledged Kotlin by making it the official language of Android app development in 2019.
Here is the discussion, which is the better option for Android App Development. Let’s begin-
JAVA
Java is a class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. Java has been released in 1995, it is the language Android itself is built on and has been hugely revered among Android developers. It has been one of the most popular languages for software development, for years.
This language allows creating any program and supports almost all types of machines, and OS X be it Android, Windows, or Linux.
KOTLIN
Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference. Kotlin is designed to interoperate fully with Java, and the JVM version of Kotlin’s standard library depends on the Java Class Library, but type inference allows its syntax to be more concise.
Android developers can use one integrated development environment (IDE) to develop with Kotlin on all platforms. With Kotlin you can write significantly less code when compared with Java. Fewer lines of code imply smaller file sizes for Kotlin, compared to Java equivalents.
If you are a complete amateur who wants to learn Android app development and on-demand mobile app development, then we’ll recommend Java for first, but if you’re a Java developer and wants to jump into the productive market of Android app development, then our recommendation is Kotlin.
Firstly, as an amateur programmer, you can start your career as an Android developer, but if you start with an established programming language like Java, you’ll have a bigger community which directly invites more job opportunities.
Secondly, Java has a huge community of developers which arranges more solutions when you are stuck. As a beginner, you’re going to face a lot of technical problems you might not know how to resolve. When you start Google the things, you find the answer; the same cannot be said for Kotlin, which seems still new programming language.
If you’re a Java Developer, it’s the best option to learn Kotlin programming language because it definitely improves your productivity. Kotlin targets several platforms, including the JVM, and is fully interoperable with Java.
Kotlin VS JAVA
- Performance and Compile Time
Kotlin shows slower compilation speed than Java in most of the cases. But Kotlin provides the ability to develop a class with new functionality without having to inherit from a class.
Java compilation time is comparatively fast. Java is to create a background thread for the long-running or intensive work. However, managing multiple threads leads to an increase in the complexity as well as errors in the code.
- Null Safety
Kotlin has inbuilt Null-safety, the NullPointerException is largely responsible for Android development mistakes. Kotlin resolves this problem easily by fusing inherent null safety.
Java has been using traditional null checking which is apt to human error. It does not support Null safety as this was included in recent updates.
- Development Speed
Kotlin has seen explosive growth in Android development and after hosting KotlinConf only twice, the conference has become something of an institution in the developer community.
Java’s code development speed is comparatively faster.
- Lambda Expressions
Kotlin has native Lambda support which is essentially anonymous functions that can be treated as values.
Java, higher-order functions are implemented using Callables. Lambdas expressions are introduced in Java 8.
- Community Support
Kotlin is still raising a lot in popularity but it has a limited support community as it is younger than Java. Fewer people are using Kotlin, it doesn’t offer as many learning resources or tools.
Java is still remaining vast programming language so the community circle is bigger than Kotlin. It’s natural that a large number of successful projects, higher the chances are that someone has already solved an issue your development team might be facing.
Final Words
Both programming languages Java and Kotlin have their advantages over the other. Kotlin has powerful features and therefore Java. They both bind us to treat more instantaneous versions.
