Hello All,
I am using IDEA 15.0.4 to debug a scala program. It is strange to me that the
results were different when I debug or run the program. The differences can be
seen in the attached filed run.jpg and debug.jpg. The code lines of the scala
program are shown below.
Thank you all
-------
import scala.collection.mutable.ArrayBuffer
object TestCase1{
def func(testtttt:Iterator[(Int,Long)]): Iterator[(Int,Long)]={
println("in")
val testtttt1=testtttt.flatmap{
case(item,count)=>
val newPrefix=item
println(count)
val a=Iterator.single((newPrefix,count))
func(a)
val c = a
c
}
testtttt1
}
def main(args: Array[String]){
val freqItems = ArrayBuffer((2,3L),(3,2L),(4,1L))
val testtttt = freqItems.toIterator
val result = func(testtttt)
val reer = result.toArray
}
}
