Question

Is there a simple way to convert a Scala object to the string representation given in the REPL? For example, for Array(2, 3, 5), I’d like to get the string "Array(2, 3, 5)", and for Stream from 2, I’d like to get "Stream(2, ?)".

Answer 1

The REPL uses the toString method to generate its string representations of values. Thus:

Array(1, 2, 3).toString      // => "Array(1, 2, 3)"

This works on all versions of Scala (2.7, 2.8, etc).
