How to convert a java.util.List to a Scala list

Question

I have this Scala method with below error. Cannot convert into a Scala list.

 def findAllQuestion():List[Question]={
   questionDao.getAllQuestions()
 } 
         


        

Answer 1

You can simply convert the List using Scala's JavaConverters:

import scala.collection.JavaConverters._

def findAllQuestion():List[Question] = {
  questionDao.getAllQuestions().asScala
}
