Scala .readInt Console Deprecated

Question

The scala command line interpreter shows:

scala> Console.readInt
warning: there was one deprecation warning; re-run with -deprecation for details
res0: Int = 65

Is it Console.readIntreally obsolete? If so, what is the correct way to enter data?

I am using scala version 2.11.7 on OS X 10.10.5.

Answer 1

In Scala 2.11 you can use

scala.io.StdIn.readInt()

or

scala.io.StdIn.readLine().toInt

Answer 2

As suggested by REPL, run scala -deprecationto get more information:

Answer 3

Tick Scala Api

(Since version 2.11.0) Use the method in scala.io.StdIn

It also has a method. readInt

Answer 4

Or you can use import to warn:

import scala.io.StdIn._
val name = readLine("Your name:")
val age = readInt()
printf("Your name: %s, your age: %d\n", name, age)
