I understand the problem, it’s simple, we are just missing the option to change the language while creating a new app. And Java will still be relevant for many years to come so there shouldn’t be major worries about any app written in it becoming obsolete in the foreseeable future. Development time can be shortened using Kotlin, which could lower the project costs. But since incremental builds are far more common in Agile software development, that Java advantage is usually neutralised. For complex, large apps, it can make sense to program with Java because it might be easier to find Java developers to work on them.
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 achieves this by eliminating unnecessary boilerplate code, such as type declarations and semicolons, and using more natural language constructs.
Kotlin is a statically typed language, meaning the variable type must be known at compile time. This can be beneficial for catching errors early on, but can also be more difficult to understand than dynamically typed languages. Kotlin has better support for functional programming like lambda expressions and higher-order functions. Kotlin is a high-performance, effective programming language that can also do a lot. Java is a long-standing powerhouse with a huge community. When it comes to which programming language is better, one thing can be said with certainty – it is probably the one the development resources available have the most expertise in.
Both help you identify which variable can be null and help you make sure the correct check is implemented. Kotlin, on the other hand, provides null safety variables where the variable must be nullable if the value can be null. These are just some of the features that make it safe to affirm that, yes, Kotlin is better than Java for Android development and is likely to dominate in the future. Java is more limited to the concept of object-oriented programming.
- Even then, using static for global variable should be simple enough.
- Some things happen automatically and it can be hard to understand what is going on.
- For general-purpose programming, Java gains the upper hand.
- Both Kotlin and Java compile to bytecode that runs on the JVM, which means they have similar performance characteristics.
- In conclusion, the debate over which language is better is not straightforward and will probably result in exciting discussions.
- It is difficult to compare Kotlin and Java in terms of difficulty because both languages are somewhat similar.
Kotlin experienced a further surge in adoption when Google officially made the language its recommended choice for Android app development in 2019 – Android’s Kotlin-first approach. Kotlin is a cross-platform, statically typed programming language initiated and developed by the company JetBrains. As a language, Kotlin leans heavily on Java and one of Kotlin’s goals was to achieve the same high compilation speed as Java. Java is a general-purpose programming language; it is not confined to machine applications.
As can also be seen in the graph below, more than 50% of new Android apps published on the Google Play store today are developed using Kotlin as the outbound programming language. Of the top 500 Android apps from the American Google PlayStore, about 87% have been developed using Kotlin. Some top apps including Uber, Evernote and Pinterest have even migrated from Java to Google’s newly preferred programming language. Java is an object-oriented programming language developed by Sun Microsystems and first published in 1995. The company, which was acquired by Oracle in 2010, published the Java programming language as part of the suit of Java technologies they developed.
Declaring variable data type has some advantages, like easy identification of some types of error, optimizing memory, and increasing the speed of arithmetic processing. Kotlin is a tool-friendly language since it can be written and converted from Java using IntelliJ, NetBeans, Eclipse, and other IDEs. Finally, Kotlin has a smart cast feature, which reduces the application’s cost and enhances its speed and performance. Kotlin has an interoperable language feature that makes it possible to call Java code.
On the other hand, Kotlin has features such as type inference and data classes that can make it more concise and easier to read than Java. However, the exact figures can vary depending on the developer’s location, industry, and experience level. According to data from Glassdoor, the median salary for a Java developer in the United States is around $95K per year, while the median salary for a Kotlin developer is $105K per year. Android apps can be written using Kotlin, Java, and C++ languages. The
Android SDK tools compile your code along with any data and resource
files into an APK, an Android package, which is an archive file with
an .apk suffix.
However, Kotlin has more laconic constructions, which allow a developer to type less code. Java is renowned for its WORA feature, meaning “write once run anywhere”. Java creates static members once that can be shared by all instances of kotlin development team the class. After programming in Java, I was really drawn in by the succinct and simple syntax of Kotlin. I did see Scala is a JVM compatible language and the syntax is very reminiscent of Java, but I wanted to try something different.
