question: public void addSetAmmoTo ( String s ) { int ewSpot = s . indexOf ( ':' ) ; int amSpot = s . indexOf ( '-' ) ; if ( s . isEmpty ( ) || ( ewSpot < 1 ) || ( amSpot < ewSpot ) ) { return ; } int loc = Integer . parseInt ( s . substring ( 0 , ewSpot ) ) ; int slot = Integer . parseInt ( s . substring ( ewSpot + 1 , amSpot ) ) ; int setTo = Integer . parseInt ( s . substring ( amSpot + 1 ) ) ; ammoSetTo . add ( new SetAmmoTo ( loc , slot - 1 , setTo ) ) ; }
target:  Converts 2:1-34 to Location 2 Slot 1 set Ammo to 34
