Describe differences between Apex and traditional Programming Languages like Java.

Click the card to flip 👆

1.) Traditional Programming Languages are fully flexible, and allow you to tell the system to do just about anything. Apex is governed, and can only do what the system allows.
2.) Apex is case-insensitive
3.) Apex is on-demand, and is compiled and executed in the Cloud (i.e. on the server)
4.) Apex requires unit testing for deployment into a Production environment
5.) Apex is not a general-purpose Programming Language. It can only be used on the Force.com platform.

What are the two primary components of Apex code?

Apex Classes and Apex Triggers

What is an Apex Class?

An Apex Class is a template or a blueprint from which Apex objects are created.

What is an Apex Trigger?

A procedure that automatically executes during a DML operation.

What are the three types of FOR() loops that Apex code supports?

1.) Traditional FOR() loops
2.) List Iteration FOR() loops
3.) SOQL FOR() loops

What are the three types of Collection data types in Apex code?

1.) Lists
2.) Maps
3.) Sets

What are Collections used for in Apex code?

Collections are used to store groups of elements, such as primitive data types, or sObjects.

Where are the three areas where you can develop Apex code?

1.) The Force.com IDE
2.) The Developer Console
3.) The Setup menu

What conditional statements does Apex support?

What conditional statements are not supported by Apex?

1.) case

What is the sObject data type?

The sObject data type is a generic data type that is the parent class for all standard and custom objects in Apex.

What are two data types that are unique to Apex?

1.) sObject
2.) ID

What is a List?

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).

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.

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.
