Printing array in Scala
arrays, scala
Solution
`mkString` will convert collections (including `Array`) element-by-element to string representations.
println(a.mkString(" "))
is probably what you want.
Problem
I am having problem with most basic Scala operation and it is making me crazy. ``` val a = Array(1,2,3) println(a) and result is [I@1e76345 println(a.toString()) and result is [I@1e76345 println(a.toString) and result is [I@1e76345 ``` Can anyone tell me how to print array without writing my own function for doing that because that is silly. Thanks!
