There's more...

In Kotlin, all the exceptions are unchecked, which means that we don't need to apply try–catch at all. This is quite different than Java, where if a method throws an exception, we need to surround it with try–catch.

Here's an example of an IO operation in Kotlin:

fun fileToString(file: File) : String { //readAllBytes throws IOException, but we can omit catching it fileContent = Files.readAllBytes(file) return String(fileContent) }

As you can see, we don't need to wrap things with try–catch if we don't want to. In Java, we couldn't proceed without handling this exception.
