Avoid Switch statement redundancy when multiple Cases do the same thing?

Question

I have multiple cases in a switch that do the same thing, like so: (this is written in Java)

 case 1:
     aMethod();
     break;
 case 2:
     aMethod();
     b         


        

Answer 1

Sure, you can allow case clause sections for 1 & 2 to 'fall through' to clause 3 and then break out of the switch statement after that:

case 1:
case 2:
case 3:
     aMethod();
     break;
case 4:
     anotherMethod();
     break;
