Contains/IndexOf Method For Lists

Salesforce Platform, Apex & Visualforce

It would be nice to have either a contains or indexOf method for a List collection.

Instead of this code:

for(Id IdToUse: ListOfIDs) {
   if(IdToUse == IdToCompare) { return true; }
}
return false;

You could simply use this:

return (ListOfIDs.indexOf(IdToCompare) > -1);

It would make working with Lists a lot more efficient.

    List.contains(Object) and List.indexOf(Object) are now available in Spring18. Make sure your apex classes are on API v42.0.
