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 :)
