Not Understanding The Null Error Here In KOTLIN
var adam :String? = "i love MY cat"
adam = null
print(adam?.uppercase())
**So im getting an error at the
.uppercase()
and its saying
** `<html>Overload resolution ambiguity:<br/>public inline fun Char.uppercase(): String defined in kotlin.text<br/>public inline fun String.uppercase(): String defined in kotlin.text ,`
and if i remove the ? from print(adam?.uppercase()) its giving me this
<html>None of the following function`your text`s can be called with the arguments supplied:<br/>public inline fun Char.uppercase(): String defined in kotlin.text<br/>public inline fun String.uppercase(): String defined in kotlin.text
So I'm kinda confused because I'm declaring the var as a nullable String so why is it Giving An Error when I'm saying its null?
