Retrieving a Variable output from IF or ELSE condition in KOTLIN
I am trying to retrieve the output value from else condition in Kotlin. I am not sure how to store the data outside If or Else condition. Any help is appreciated.

else
{
var data=db.readData()

for (i in 0..data.size - 1)
{
var data=db.readData()
var output=data.get(i).name
println("Result is $output")
}

}

//Need to Get Output here
var test=output??
