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

Below is the best you can do

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