object BibaoDemo {
  def main(args: Array[String]): Unit = {
    val f: String => String = makeSuffix(".jpg")
    println(f("d.jpg"))
    println(f("c.jpg"))
  }

  def makeSuffix(suffix: String): String => String = {
    (filename: String) => {
      if (filename.endsWith(suffix)) {
        filename
      } else {
        filename + suffix
      }
    }
  }

}

结果：

d.jpg
c.jpg
