problem with Character/isLetter

[AJ Sterman]

(Character/isLetter "x")
#<CompilerException java.lang.IllegalArgumentException: No matching
method found: isLetter (NO_SOURCE_FILE:79)>

i tried a few "use ' " and there was no avail

Thank you for trying to help

isLetter accepts single characters, you gave it a string with a length of one.
The error is caused by reflection when clojure searches for a function
with the signature isLetter(String)

To complete the thought,

user=> (Character/isLetter \x)
true
user=> (Character/isLetter (.charAt "x" 0))
true

or:

user=> (first "x")
\x
user=> (Character/isLetter (first "x"))
true
