Scala Array和List转ListBuffer

用to[ListBuffer]方法

scala> val l = List(1,2,3)
l: List[Int] = List(1, 2, 3)
scala> l.to[ListBuffer]
res1: scala.collection.mutable.ListBuffer[Int] = ListBuffer(1, 2, 3)

如何删除ListBuffer元素

val x = ListBuffer(1, 2, 3, 4, 5, 6, 7, 8, 9)
x -= 5

如果ListBuffer中有相同多个元素 只能删除一个

批量删除相同元素

val te = ListBuffer(1, 4, 6, 7, 8, 9,1)
for (x<-te){
    if (x==1) te-=1
}
print(te)

te: scala.collection.mutable.ListBuffer[Int] = ListBuffer(1, 4, 6, 7, 8, 9, 1)
ListBuffer(4, 6, 7, 8, 9)
