<h1>Further notes on Kotlin<a class="headerlink" href="#further-notes-on-kotlin" title="Permalink to this headline">¶</a></h1>
|
|
<p>Corda is written in a language called <a class="reference external" href="https://kotlinlang.org/">Kotlin</a>. Kotlin is a language that targets the JVM
|
|
and can be thought of as a simpler Scala, with much better Java interop. It is developed by and has commercial support
|
|
from JetBrains, the makers of the IntelliJ IDE and other popular developer tools.</p>
|
|
<p>Kotlin is a relatively new language and is extremely easy to learn. It is designed as a better Java for industrial
|
|
use and, as such, the syntax was carefully designed to be readable even to people who don’t know the language, after only
|
|
a few minutes of introduction. Additionally, at R3, we find that all of our developers are up to productive writing speed
|
|
in Kotlin within their first week.</p>
|
|
<p>Due to the seamless Java interop the use of Kotlin to extend the platform is <em>not</em> required and the tutorial shows how
|
|
to write contracts in both Kotlin and Java. You can <a class="reference external" href="https://medium.com/@octskyward/why-kotlin-is-my-next-programming-language-c25c001e26e3">read more about why Kotlin is a potentially strong successor to Java here</a>.</p>
