+When you start migrating your Java code to Kotlin, you will encounter multiple subtle changes that might catch you off guard. I'll document some of these gotchas that I and other people I follow have found and written about.
+
+## Splitting strings
+
+Java's `java.lang.String#split` [method](https://docs.oracle.com/javase/8/docs/api/java/lang/String.html#split-java.lang.String-) takes a `String` as it's first argument and creates a `Regex` out of it before attempting to split. Kotlin, however, has two variants of this method. One takes a `String` and uses it as a plaintext delimiter, and the other takes a `Regex` behaving like the Java method we mentioned earlier. Code that was directly converted from Java to Kotlin will fail to accommodate this difference, so be on the lookout.
