IntelliJ中的Scala快速修复

Question

I have the following code:

    var i = sqrt (30)

To use the sqrt function in Scala I have to import scala.math.sqrt
I am using IntelliJ and I am new in it and Scala. In Eclipse when programming java, when I use a function where the package is not imported in the source, Eclipse recommends the package and I can insert it by a simple mouse click.
Is something similar possible in IntelliJ when programming Scala?

Answer 1

Yeah, Intellij supports this kind of feature. Usually when an import is available, you can just press Alt+Enter and it will be autocompleted.

With that specific class it may fail for some reason, this system is not perfect, but when there are no implicits or ambiguity, it should work really well.
