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

It's called the "fall through" pattern:

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