Convert java.lang.Boolean to Scala Boolean

Question

I am currently working on a Scala application which utilizes Spring-Boot and Swagger to send & receive REST-calls.

Swagger and Spring-Boot are pure Java-projects an

Answer 1

1. You don't need to write out java.lang.blah every time in

   ParamsAsJava(java.lang.Boolean.FALSE, java.lang.Boolean.TRUE)
   

   Just use

   ParamsAsJava(false, true)
   

   instead. Autoboxing hasn't gone anywhere.

2. to get rid of toScala, define an implicit conversion in Params companion object:

   object Params {
     implicit def params_j2s(p: ParamsAsJava): Params = p.toScala()
   }
   

   now you can write:

   val test1: Params = ParamsAsJava(true, false)
   

   and, of course, if you don't define this variable in vacuum, but pass it to a method instead, the right type will be inferred automatically, and the object will be converted implicitly.

3. No need to use parens () in def toScala(), the method has no side effects.
