Write a program to sort an array elements

object demo{
def main(args: Array[String])
{
   val data = Array(1,2,3,2,9,2,1,4)
   println("Input")
   println(data.mkString(","))
   for(i <- 0 until data.length-1)
   {
              for(j<-0 until data.length-i-1)
              {
                     if(data(j)>data(j+1))
                     {
                        var temp = data(j)
                        data(j)=data(j+1)
                        data(j+1)=temp
                      }
               }
   }
        println("Sorted elements in Array")
        println(data.mkString(","))
 }
}
