For-each loop

Of course, if you're a bit familiar with Java, you may argue that the previous code could be improved by using a for-each construct instead:

final String word = "Word";

for (Character c : word.toCharArray()) {
    System.out.println(c);
}

The same in Kotlin would be:

val word = "Word"

for (c in word) {
    println(c)
}
