Switch on key
only and append the value
to the correct array. You can switch on multiple keys at once.
switch(key){
case "BEL", "LIE", "BGR":
europeanCapitals.append(value)
.
.
}
Make sense?
Steve.

otherCapitals
array is thedefault
condition for theswitch
statement so do the other array completions first.
