Range class : java interoperability

Question

Why does not this work? In a Java code:

import scala.collections.immutable.Range;

// ...

Range r = Range.apply(0, 10)

Eclipse says:

The method apply(int) in the type Range is not applicable for the arguments (int, int)

And SBT says:

error: method apply in class Range cannot be applied to given types;

However, there is an apply(Int, Int) method in the collections.immutable.Range object of the Scala API.

Answer 1

That's because you're calling the apply(int) method from the Range class. You should be calling apply(int,int) from the companion object:

import scala.collection.immutable.Range$;
// ...
Range r = Range$.MODULE$.apply(0, 10)
