Question

Is this allowed in Scala code:

DomNode node = node.getFirstChild()

where DomNode is Java type from external java library and getFirstChild() is defined on DomNode type.

I am porting existing java program to scala and it would be very convenient if I leave original java declerations as is to minimize porting efforts.

Answer 1

You can use Java classes in a Scala program, but you would ofcourse have to use Scala syntax:

val node: DomNode = node.getFirstChild()

You cannot use Java syntax in the form Type variableName.

edit (thanks to ericacm) – You can also just specify

val node = node.getFirstChild()

so you don’t have to specify the type of node explicitly; you can let Scala infer the type.
