Scala Console.readInt已弃用

Question

scala的命令行解释器显示:

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

难道Console.readInt真的过时？如果是,采取输入的正确方法是什么？

我在OS X 10.10.5上使用Scala版本2.11.7.

Answer 1

在Scala 2.11中,您可以使用

scala.io.StdIn.readInt()

要么

scala.io.StdIn.readLine().toInt

Answer 2

根据REPL的建议,运行scala -deprecation以获取更多信息:

scala -deprecation
Welcome to Scala version 2.11.2 (OpenJDK 64-Bit Server VM, Java 1.7.0_79).
Type in expressions to have them evaluated.
Type :help for more information.
