Here’s a little Kotlin joinToString
example. First, a sample list to work with:
val nums = listOf(1,2,3,4,5)
Then here’s the joinToString
example:
nums.joinToString(
separator = ", ",
prefix = "[",
postfix = "]",
limit = 3,
truncated = "there’s more ..."
)
When you put all of that code in the Kotlin REPL you’ll see this result:
[1, 2, 3, there’s more ...]
A few notes about that example:
- You can see the separator, prefix, and postfix in the output
- Only the numbers 1, 2, and 3, are printed because the limit is set to 3
- The “
there’s more...
” truncated text is printed after the third value
In summary, I hope this Kotlin joinToString
example is helpful.
