Salesforce Certified Platform Developer I –
Apex/ 299 Quizzes & Correct Ans.
What is a List? - Answer: A List is an ordered collection of elements of a single
data type. Elements added to a List are assigned an implicit index, and therefore,
Lists can contain non-unique values (i.e. elements can be duplicated within a List).

What is a Set? - Answer: A Set is an unordered collection of unique elements.
There are no indexes assigned to elements in a Set, and therefore, elements in a
Set much be unique.

What is a Map? - Answer: A Map is a collection of key-value pairs. Keys must be
unique, but Values can be repeated. With Maps, we supply the index, unlike Lists,
where the index is automatically applied when an element is added.

Are Apex Arrays the same as Java Arrays? Why or why not? - Answer: While Apex
Array notation seems the same as Java Array notation, they are internally
different. Apex Arrays can be dynamically resized, while Java Arrays cannot be
dynamically resized.

//Array notation
Account[] accounts = new Account[] {acc1,acc2,acc3};

//List notation
List<Account> accounts = new List<Accounts>;
accounts.add(acc1);
accounts.add(acc2);
accounts.add(acc3);

Are Lists also Arrays? - Answer: No. Lists are not Arrays, but they can be
syntactically referenced as Arrays.

,How can you iterate over a Map? - Answer: First retrieve the key set by using the
Map.keySet() method. Then, use a FOR() loop to iterate through the key set to
access and work with each value in the Map.

What do classes consist of? - Answer: Methods and Attributes
