object ScalaTest{
    def main (args: Array[String]){
        var i =0

        while(i<=10){
            println(i)
            i +=1
        }
    }
}

When i do 

c:\ Scalac ScalaTest.scala \\ it goes to the next line but
c:\ Scala ScalaTest.scala \\ Nothing is happening cursor is blinking in the next line but no response.

What am i doing wrong here. Not able to see the output or anything. Please help.

The file you should execute with the scala command after compiling is not the source file but the resulting binary file from scalac.

If you take a look at: http://www.scala-lang.org/old/node/166

You should then try:

  scalac ScalaTest.scala

  scala ScalaTest

I tried your code in the REPL console and it's working ok. However, it might not be the most idiomatic Scala code ever.

It's a good approach to take a look at Range and trying something like:

  (0 to 10).foreach(println)

Which produce the same result without a mutable variable

  • Hi Aurelien, Thank you very Much Actually "scala ScalaTest" Worked. But for the "Scala ScalaTest.scala" the console waited for about 45 mins then it gave be the below Error: "There is insufficient memory for the Java Runtime Environment to continue.Native memory allocation(malloc) failed to allocate 1048576 bytes for AllocateHeap.. Could not connect to compilation daemon after 300 attempts" .- I think .. may be due to no Ram Memory allocation. – StandForTheRight Sep 19 '15 at 15:51
