Quite simple with a closure   def map                 iPhone   iWebOS               Android   2 3 3               Nokia   Symbian               Windows   WM8                map each  k  v - gt  println    k    v

Alternatively you could use a for loop as shown in the Groovy Docs   def map     a  1   b  2   c  3  for   e in map         print  key     e key   value     e value         Result  key   a  value   1 key   b  value   2 key   c  value   3      One benefit of using a for loop as opposed to an each closure is easier debugging  as you cannot hit a break point inside an each closure  when using Netbeans

When using the for loop   the value of s is a Map Entry element   meaning that you can get the key from s key and the value from s value
