scala调用java的方法,返回了一个对象链表List,在scala中遍历该链表获取指定Student的名字name

class Student {
  private int no;
  private String name;
  public int getNo() { return no; }
  public String getName() { return name; }   
}

List getStudents(){
  ...
  return studentList;
}

getStudents().find(_.getNo == 1).map(_.getName)

val votes = Seq(("scala", 1), ("java", 4), ("scala", 10), ("scala", 1), ("python", 10))
 val orderedVotes = votes
   .groupBy(_._1)
   .map { case (which, counts) =>
     (which, counts.foldLeft(0)(_ + _._2))
   }.toSeq
   .sortBy(_._2)
   .reverse

val votesByLang = votes groupBy { case (lang, _) => lang }
 val sumByLang = votesByLang map { case (lang, counts) =>
   val countsOnly= counts map { case (_, count) => count }
   (lang, countsOnly.sum)
 }
 val orderedVotes = sumByLang.toSeq
   .sortBy { case (_, count) => count }
   .reverse

 val orderedVotes = {
   val votesByLang = ...
   ...
 }
