- Click the convert button.
- The resulting Kotlin code from the conversion will be displayed in the output box.
Examples
The following are examples of code conversion from Scala to Kotlin using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.
Example 1 - Is String Palindrome
Program that checks if a string is a palindrome or not.
Scala
Kotlin
Example 2 - Even or Odd
A well commented function to check if a number if odd or even.

Key differences between Scala and Kotlin
| Characteristic | Scala | Kotlin |
|---|---|---|
| Syntax | Scala has a more complex syntax than Kotlin, with a focus on functional programming concepts. | Kotlin has a simpler and more concise syntax than Scala, with a focus on readability and ease of use. |
| Paradigm | Scala is a multi-paradigm language that supports both object-oriented and functional programming. | Kotlin is a statically-typed, object-oriented language that also supports functional programming concepts. |
| Typing | Scala has a strong static type system that allows for type inference and type safety. | Kotlin also has a strong static type system with support for type inference and null safety. |
| Performance | Scala has good performance due to its use of the JVM and support for functional programming concepts. | Kotlin also has good performance due to its use of the JVM and support for inline functions. |
| Libraries and frameworks | Scala has a large number of libraries and frameworks available, including Akka, Play, and Spark. | Kotlin has a growing number of libraries and frameworks available, including Ktor, Spring, and Android KTX. |
| Community and support | Scala has a large and active community with good support from the Scala Center and other organizations. | Kotlin also has a growing and active community with good support from JetBrains and Google. |
| Learning curve | Scala has a steep learning curve due to its complex syntax and support for advanced functional programming concepts. | Kotlin has a relatively easy learning curve due to its simple syntax and similarity to Java. |
Frequently Asked Questions
How do I convert Scala to Kotlin?
Paste your Scala code into the input box, confirm the languages are set to Scala and Kotlin, and click Convert. CodeConvert AI analyzes your Scala code and generates equivalent Kotlin code in seconds, preserving the original logic and structure.
What are the main differences between Scala and Kotlin?
Scala and Kotlin differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Scala construct to its closest Kotlin equivalent. See the comparison table below for the key differences between Scala and Kotlin.
Is the converted Kotlin code accurate?
The AI produces high-quality Kotlin code that preserves the behavior of your original Scala code and follows Kotlin conventions. It handles common patterns, data structures, and idioms for both Scala and Kotlin. For large or performance-critical code, review and test the Kotlin output before using it in production.
Can I convert an entire Scala project to Kotlin?
You can convert Scala files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Scala to Kotlin. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Kotlin back to Scala?
Yes. CodeConvert AI converts in both directions, so you can convert Kotlin to Scala just as easily using our Kotlin to Scala converter. Try the Kotlin to Scala Converter
Is the Scala to Kotlin converter free, and do I need to install anything?
Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert Scala to Kotlin without an account for up to 5 conversions per day. Sign in for free for higher limits.
What are the benefits of signing in?
Signing in unlocks CodeConvert AI's Pro converter with more powerful AI models, a built-in chat assistant, code execution, saved conversion history, and personal notes. Every free account includes 5 credits and supports up to 25,000 characters of input per conversion, with no credit card required.
