Match “fallthrough”: executing same piece of code for more than one case?

Question

What is the Scala\'s way to write the following code:

 int i;

 switch(i) {
   case 1:  
         a();
         break;

   case 2:
   case 15:
        b();
          


        

Answer 1

According to this conversation there is no fallthrough, but you can make use of |.

This should do the trick:

i match {
  case 1  => a    
  case 2 | 15 => b
                 c
  case _ => foo        
}
