Strip whitespace from a string/Top and tail: Difference between revisions

It is worth poiting out that Kotlin, unlike Java, has <code>String.trimStart</code> and <code>String.trimEnd</code>. More importantly though, Kotlin’s <code>String.trim</code> actually trims whitespace as defined by Unicode, whereas Java’s just strips Unicode control characters.

<lang kotlin>fun main(args: Array<String>) {

val s = " \tRosetta Code \r \u2009 \n"

println("Untrimmed => [$s]")

println("Left Trimmed => [${s.trimStart()}]")

println("Right Trimmed => [${s.trimEnd()}]")

println("Fully Trimmed => [${s.trim()}]")

Untrimmed => [ Rosetta Code  

]

Left Trimmed => [Rosetta Code  

]

Right Trimmed => [ Rosetta Code]

Fully Trimmed => [Rosetta Code]
