We all know map is very much required in SFDC, As a developer we should be familiar with map uses. This post is all about to add list of records to a map. Map<Id,Account> account_map =  new Map<Id,Account>(); public static void addinglisttoMap(List<Account> accList){ for(Account acc:accList){ account_map.put(acc.id,acc); } }  Normally we used to do like above, where processing time will be more(CPU execution time will be more) because we are iterating over a for loop to construct a map.  I will tell you the best way to construct the map where we can avoid iteration.  public static void addinglisttoMap(List<Account> accList){ Map<Id,Account> account_map =  new Map<Id,Account>(accList); } Advantages-  Processing time will be very less No of character in apex class is also less.  Hope it will be helpful.  Keep coding and exploring :)
