我想用stream生成多个句子。我现在能造出1个句子。

def main(args: Array[String]): Unit = {
    println((generateSentence take 1).mkString)
  }

这是我到目前为止得到的结果

现在如果我想取两个句子，流将继续写入第一个句子
现在，我如何在该流中生成多个句子到一个数组（或一个列表）中呢？
我想把字体改成 Stream[List[String]] 但我不知道如何才能添加正确的生成方式（它给了我 Exception in thread "main" java.lang.StackOverflowError )
使用流[list[string]]代码：

/**
   * Generate one sentences between 2 and 25 words
   * @return
   */
  def generateSentence : Stream[List[String]] = {
    def sentences : List[String] = {
      sentences.::((generateWord take between(2, 25)).mkString) /* This line gave me the Exception StackOverflow */
    }
    Stream continually sentences
  }

我写的原始代码

/**
   * Generate one word between 2 and 25 char
   * @return
   */
  def generateWord: Stream[String] = {
    def word : String = {
      (Random.alphanumeric take between(2, 25)).mkString.concat(" ")
    }
    Stream continually word
  }

  /**
   * Generate one sentences between 2 and 25 words
   * @return
   */
  def generateSentence : Stream[String] = {
    def sentences : String = {
      (generateWord take between(2, 25)).mkString 
    }
    Stream continually sentences
  }

  /* This one is from the Random library, as it was introduced with 2.13 (so I just backported it into my 2.12)*/

  def between(minInclusive: Int, maxExclusive: Int): Int = {
    require(minInclusive < maxExclusive, "Invalid bounds")

    val difference = maxExclusive - minInclusive
    if (difference >= 0) {
      Random.nextInt(difference) + minInclusive
    } else {
      /* The interval size here is greater than Int.MaxValue,
       * so the loop will exit with a probability of at least 1/2.
       */
      @tailrec
      def loop(): Int = {
        val n = Random.nextInt()
        if (n >= minInclusive && n < maxExclusive) n
        else loop()
      }
      loop()
    }
  }
}
