Q:

java to scala conversion - generic typings for r-tree lost?

I want to use https://github.com/davidmoten/rtree to create
RTree<String, Point> tree = RTree.create();
tree = tree.add("someStuff", Geometries.point(10,20));

In scala I tried to
val tree = RTree.create // note no generics here. Unsure how to add them
tree.add("someStuff", Geometries.point(10,20))

This results in 
cannot resolve symbol 'add' when trying to compile the Scala code.

A:

This should fix it:
val tree: RTree[String, Point] = RTree.create[String, Point]()
tree.add("someStuff", Geometries.point(10,20))
