scala - What's wrong with the expression `new ListBuffer.empty[Int]` -

i found works well:

val buf = scala.collection.mutable.listbuffer.empty[int] 

but, doesn't work:

import scala.collection.mutable.listbuffer val buf = new listbuffer.empty[int] 

the compiler complains:

error:(2, 32) type empty not member of object scala.collection.mutable.listbuffer lazy val buf = new listbuffer.empty[int]                               ^ 

does have ideas this?

listbuffer.empty isn't constructor, it's function returns empty listbuffer.

there's no need new keyword.
