Nevertheless, Java will remain a popular programming language in the world. Since it is interoperable with Java, people find it easy to adopt. Developers with Java projects can add functionality using https://wizardsdev.com/en/vacancy/qa-automation-engineer-javakotlin/ Kotlin code without migrating their entire project. Therefore, Java and Kotlin developers can seamlessly collaborate. Functional programming is a feature that sets these two languages apart.
As a statically typed programming language, Kotlin makes use of a range of function types for representing functions. Moreover, it comes with a set of specialized language constructs, such as the lambda expressions. 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. It is also an object-oriented language that operates on several devices, including computers, mobile devices, and gaming consoles.

This means determining which language will better suit your application in the long run. Java has been around for decades and continues to evolve and grow in popularity, whereas Kotlin is relatively new, with a smaller community. Additionally, Java has other features, including a ternary operator, primitive types, and implicit conversions. Before detailing Kotlin’s and Java’s features, we’ll examine their performance and memory consumption as these factors are generally important considerations for developers and clients. Java is a multi-platform, object-oriented, and network-centric, programming language. It also used as a computing platform, and it was first released by Sun Microsystem in 1995.
James Gosling designed Java, and its major implementation was OpenJDK. Java is the primary choice for most developers regarding Android application development, as Android itself is written in Java. Java is a multi-paradigm, class-based object-oriented, imperative-style programming language that first appeared in 1995. Java’s syntax is influenced by C++ and C, which means that developers can easily jump between languages without much friction, leading to a lower barrier to entry.
Kotlin’s Edge Over Java– Java vs Kotlin
For example, in Kotlin, all variables are non-null by default, meaning that they cannot hold a null value unless explicitly declared as nullable using the “?” operator. This helps to prevent null-related errors at compile-time, rather than waiting until runtime. In Java, it’s possible to have null values assigned to a variable, which can lead to null pointer exceptions at runtime. Kotlin, on the other hand, requires you to explicitly define whether a variable can be null or not. This makes it easier to avoid null pointer exceptions during runtime. As you can see, the Kotlin version is much shorter and more expressive.
- Kotlin, on the other hand, requires more cognitive investments in learning than Java.
- It is best thought of as a more feature-filled Java for Android development.
- You are unlikely to find a problem that you can solve with Kotlin and can’t with Java, and vice versa.
- This is because this Bundle is stored by the operating system in order to rebuild this Fragment in case it is destroyed.
The Kotlin feature of incorporating data classes can fix this issue. For storing data in a class, developers need to define a class using the keyword “data.” This step will automatically produce the typical boilerplate code during compile time. In the context of Kotlin vs Java for Android, the choice is obvious, and it’s Kotlin. The younger and more modern programming language ousted Java from this area.
Kotlin vs Java: Comparison Table
There are so many comparisons that are made between these two languages, let us look at some of the top comparisons. In this blog post, we’re going to compare Java and Kotlin to help you decide which one to learn. But, the introduction of Kotlin in the scene reduced the confidence that developers had in Java.
Java boasts a huge developer community because of its presence in the development arena for a long time. Therefore, you are more likely to find a resolution to your problem from the vast and helpful Java community. In Java typing, you have to explicitly specify the type (string, float, etc.) while declaring a variable. Also, to use a defined primitive variable as a different primitive type, developers have to explicitly “cast” a variable to the other type. Java users need to create a new child class if they want to extend the functionality of an existing class. This new child class not only inherits from the parent class but also offers space for extra functionality.

This is because this Bundle is stored by the operating system in order to rebuild this Fragment in case it is destroyed. So, to understand the benefits of moving from Java to Kotlin, you can go through the following infographic and identify on your own which language is more useful for your next project. To make it easy, we have also prepared an Android Java vs Kotlin infographic to give you a quick look into comparison.
It runs in JVM (Java Virtual Machine) and is usually used for backend or standalone app development. As for backend development, Java is still in the top programming languages for this purpose. Here, it doesn’t face JVM limitations and demonstrates its full potential. Add to that ton of groundwork and tools, and one of the largest developer communities worldwide. It’s possible that in the future Kotlin will prevail on the backend side too, but for now, this isn’t the case. In contrast, Kotlin replaces this complete with companion objects, top-level functions, and extension functions.
Java vs Kotlin: Which One Is Better To Learn In 2022?
It is developed by JetBrains to add some additional features to Java for mobile development. 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.
The purpose of static members is that they act as a global and shared variable within the scope of its creation such as the method of a given class. It’s unlikely that Android will stop supporting Java any time soon. To move away from Java completely would represent a monumental shift in the Android ecosystem.
