Size zero check can be replaced with 'isEmpty()'
Reports size == 0
checks on Collections/Array/String
that should be replaced with isEmpty()
.
Using isEmpty()
makes your code simpler.
The quick-fix replaces the size check with isEmpty()
.
Example:
fun foo() {
val arrayOf = arrayOf(1, 2, 3)
arrayOf.size == 0
}
After the quick-fix is applied:
fun foo() {
val arrayOf = arrayOf(1, 2, 3)
arrayOf.isEmpty()
}
