Which is better, Kotlin vs java? Let’s settle the debate

While Java and Kotlin both have ample documentation, Kotlin has a smoother learning curve. Kotlin and Java have core similarities, but each language offers different, unique features. Since Kotlin became Google’s preferred language for Android development, I’ve found extension functions and explicit nullability to be the most useful features. On the other hand, when using kotlin android development Kotlin, the Java features that I miss the most are the protected keyword and the ternary operator. Kotlin is an open-source programming language that’s often pitched as a Java replacement; it’s also a “first-class” language for Android development, according to Google. Kotlin, on the other hand, is streamlined, with some great features, and comes with a solid library.

Is Kotlin better than Java

So, if you’re starting a new Android project, Kotlin is definitely worth considering as your primary development language. “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. Part of the underwhelming code reduction is that a lot of the app code being translated consists of user interface definitions, which remain the same whether they’re in Java or Kotlin. “On average, we’ve seen a reduction of 11 percent in the number of lines of code from this migration,” said Strulovich. “We have seen much higher numbers quoted online, but we suspect these numbers are derived from specific examples.” JAR, or Java ARchive, files is a popular file format for aggregating multiple Java files into one file.

Should I learn Java before Kotlin?

On the other hand, Kotlin is a relatively new language that offers contemporary features and concise syntax, which makes it an appealing alternative for developers. With Kotlin, you can enjoy many features that aren’t available in Java. For example, Kotlin has null safety built into the language, meaning you can avoid those pesky NullPointerException errors. It also supports data classes and lambdas, which can make your code more concise and expressive. It can be used for mobile, web, server-side, desktop, and even embedded systems development.

Java, meanwhile, is an older programming language, having been introduced to the developer world back in 1995 by Sun Microsystems. It is commonly used for developing enterprise applications, mobile apps for Android devices, and server-side programming – to name but a few. Android programming language is easy to learn and also app development is cost-effective, which puts Android into great use.

Kotlin vs Java: A Quick Roundup Table

In case you are an experienced developer, you can start with Kotlin’s course that teaches everything that you need to know about it. Finally, Kotlin has better support for Android development than Java does. This includes features like null safety and Android Extensions that make developing Android applications with Kotlin much easier than with Java. Android developers enjoy the Kotlin compiler, making each Kotlin project way more efficient. On the flip side, Kotlin offers no support for checked exceptions.

Kotlin is a relatively new programming language that was first introduced in 2011 by JetBrains, a software development company that is known for its popular IntelliJ IDEA Java IDE . Autocode, developed in 1952 by Alick Glennie, was the first compiled programming language, meaning it could be directly translated into machine code. In 1957, FORTRAN was invented by John Backus for high-level scientific, mathematical, and statistical computations. People who want to learn a programming language for a career switch or start their career as a developer will also get benefitted from this post. When it comes to learning, it is better to learn Java first and then Kotlin.

Kotlin vs. Java: Null Safety

In 1949, Assembly Language was first used to simplify machine code, which was necessary for instructing computers. Every project manager should know the key factors of a language that can determine the success of app development. Java supports checked exceptions, an unexpected event or error that occurs during the run-time of program execution. When these exceptions are checked at compile-time, they’re called checked exceptions. While Kotlin and Java are object-oriented and share some similarities in syntax and features, their origins have influenced their development and design decisions. Kotlin was specifically designed to address some shortcomings of Java, such as null safety and verbosity.

At the same time, Java’s long history and widespread adoption mean it has a larger and more established ecosystem. 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. When determining if Kotlin is appropriate for Android development, there are a few considerations to keep in mind. Making sure the product team is ready to make the changeover should be the first thing to think about. A learning curve might be introduced by using a new language, rewriting the project, and project optimization.

Community Support and Learning Resources

Kotlin does away with them to aid code conciseness but it still remains favoured by many developers. In the later part of this article, I will discuss the pros and cons of each language in detail, so you can decide for yourself which language you want to learn. So if you are already a java programmer who just now wants to start developing Android apps, you can start with Kotlin. But if you are an absolute beginner getting your feet wet in the world of programming, begin with Java. Java is the bedrock of Android development and hence, helps you learn the coding etiquette and get your basics right.

Is Kotlin better than Java

Choosing the right one for your needs comes down to personal preference, and this article has gone through some of the key differences between kotlin vs java to help you pick. 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.

Functional Programming

Unlike Java, Kotlin lets developers automatically handle redundant casts without having to check type or having to cast inside a statement. As long as the cast is already checked with the ‘is operator’, smart casts in the Kotlin compiler tracks the conditions inside an ‘if expression’. Kotlin’s extension functions allow importing a reference to a View into the activity file, allowing working with that view as if a part of the activity.

  • You might also want to know what apps have been built using Kotlin and Java.
  • Some of the popular apps built using this language are Trello, Twitter, and Netflix.
  • Google’s announcement about Kotlin programming language as a future of Android development, is definitive proof that the market for Kotlin will expand more in the coming days.
  • A higher-order function is one that takes functions as parameters or returns a function.
  • The primary reason is the Open Handset Alliance made the user interface of Android OS using Java programming language.
  • Kotlin has the ability to cross-compile and run on multiple platforms, while Java is limited by its use of bytecode which can only be compiled for a single platform at once.
