I would like to find an element in a list that matches a predicate

  • 0

I would like to find an element in a list that matches a predicate and to get a default value if no elements matches the predicate. I want to do this idiomatically, without defining additional variables (one liner).
Is there something similar to getOrElse of HashMap?

    This is yet another example of why Option is great!

    The find method returns an Option, and Option has a method getOrElse that does exactly what you want. 

    scala> List(1,2,3).find(_ > 4).getOrElse(0)
res0: Int = 0

    When nothing is found, find returns None, which means the “else” value will be returned.
