推荐答案
这是我在Scala中处理 BufferedReader 的方式：
This is how I deal with a BufferedReader in Scala:
val br:BufferedReader = ???
val strs = Stream.continually(br.readLine()).takeWhile(_ != null)
阅读器的每一行都有一个字符串。如果要在一个字符串中输入它：
You will have a string for each line from the reader. If you want it in one single string:
val str = Stream.continually(br.readLine()).takeWhile(_ != null).mkString("\n")
