What would be the right way to generate an UUID in kotlin?

I used that but it uses java.util. I thought there is something built in. Thank you

Rule of thumb is, that kotlin reuses everything from java where its applicable and only adds stuff on top of it where its needed

It’s philosophy of Kotlin: Reuse everything what is available on the platform and add more idiomatic API for that if it’s required. Allows to have small stdlib and close to zero overhead

So in this case, if I want to use this around my code, is it ok to have a file Utils in which have

`fun getUUID(): String {
    return UUID.randomUUID().toString()
}`

Sure

I am learning Kotlin and don't want to pass unneeded behavior from java

but I would rename it to something like randomUUID() or randomUUIDString()

I mean there are things done different in Kotlin and some things that are done in Java don't need to be made in Kotlin. For instance instead of StringUtils have fun directly in

String.toUpperCase

or even shorter

fun getUUID() = UUID.randomUUID().toString()

@Alin B. Yup! And that's a perfect example of reusing what the platform provides but making it more idiomatic

Exactly, Kotlin doesn’t have Utils classes, because you can use much more idiomatic and convenient extensions

Thank you to all for your time.
