I strive for building happy, motivated, and productive teams and I’m enthusiastic about Kotlin, clean code, distributed systems, testing and the sociology of software development. I am Philipp Hauer and I work remotely as a Head of Engineering for Commercetools in Leipzig, Germany. I highly recommend the book Kotlin in Action.You can find the source code in my GitHub project idiomatic kotlin. If like to read more about sealed classes as an alternative to exceptions, check out the post ‘ Sealed Classes Instead of Exceptions’. If you use when as an expression the compiler even forces you to handle the error case.

Sealed class UserProfileResult Ĭontrary to exceptions (which are always unchecked in Kotlin), the compiler guides you to handle the error cases. Consequently, we can create pure functions (functions without side-effects) more easily. These features allow writing functional code in a safe, concise and expressive way. We can combine these control structures with other expressions concisely.

Expressions: Single expression functions.

Immutability: val for variables and properties, immutable data classes, copy().

In contrast to Java 8, Kotlin has way better support for functional programming: Java Idiom or Patternĭata class with immutable properties, copy()ĭelegated properties by: Delegates.observable()Īmong other advantages, functional programming allows us to reduce side-effects, which in turn makes our code…

Fortunately, many patterns are built-in right into Kotlin’s language or its standard library. In Java, we have to write quite some boilerplate code to implemented certain idioms and patterns. Kotlin’s Built-in Support for Common Java Idioms and Patterns For instance, when you create a “train wreck” by trying to squeeze everything into a single unreadable expression. If overused, they can make our code even harder to read. The parser always performs a best effort heuristic to parse the message even if it is not well formed. By doing this, you can work with SWIFT messages focusing on the data and not having to deal with low level syntax details. Moreover, some Kotlin features should be used with sound judgment. MT Parser (FIN MT to Java) The parser provides functionality to convert SWIFT messages FIN text into the Java message model. Let’s see how we can write idiomatic Kotlin code and do things the Kotlin way.Ī word of warning: The following list is not exhaustive and does only express my humble opinion. Many of them can be replaced with better alternatives that are provided by Kotlin.
