Apex - maps sets and lists - data collections
lists - orders index numbers starting with 0, 1, 2, 3,........
List<string> ListOfCities = new List<string>();
List<string> ListOfStates = new List<string> {'NY', 'LA', 'LV'}();
List<account> AccountToDelete = new List<account> ();//This will be null
List<List<Set<Integer>>> myNestedList = new List<List<Set<Integer>>>();
String [] ListOfStates = new List<string>();
Below are some most frequently used methods.
size()
add()
get()
clear()
set()
//Initialize the List
List<string> ListOfStatesMethod = new List<string>();
//This statement would give null as output in Debug logs
System.debug('Value of List'+ ListOfStatesMethod);
//Add element to the list using add method
ListOfStatesMethod.add('New York');
ListOfStatesMethod.add('Ohio');
//This statement would give New York and Ohio as output in Debug logs
System.debug('Value of List with new States'+ ListOfStatesMethod);
//Get the element at the index 0
String StateAtFirstPosition = ListOfStatesMethod.get(0);
//This statement would give New York as output in Debug log
System.debug('Value of List at First Position'+ StateAtFirstPosition);
//set the element at 1 position
ListOfStatesMethod.set(0, 'LA');
//This statement would give output in Debug log
System.debug('Value of List with element set at First Position'+ ListOfStatesMethod[0]);
//Remove all the elements in List
ListOfStatesMethod.clear();

System.debug('Set with removed value '+ProductSet);
//Check whether set contains the particular element or not and returns true or false
ProductSet.contains('HCL');

Apex - Variables and data types – strings, dates, numbers, booleans, and sObjects
Variables and data types – strings, dates, numbers, booleans, and sObjects
Data types are simply the different types of variables you can have
String bestteam = 'PortsmouthFC';
Integer numberofpoints = 3;
Decimal goalratio = 0.9;
Boolean winner = true;
Date next match = Date.today().addDays(30);
DateTime now = DateTime.now();
Contact me = [SELECT FirstName, LastName
FROM Contact
WHERE Email = 'iain.banks@email.com'
LIMIT 1];
Strings are simply text variables
Integers and decimals are used in number, currency, and percentage fields in Salesforce. Integers are for number fields without any decimal places.
Booleans are just either true or false. They’re used with checkboxes in Salesforce.

Apex - basic trigger and unit test explained
Apex - basic trigger and its unit test explained
Basic Trigger
// trigger name "addcompanyname" on "user" (sobject)
trigger addcompanyname on User (before insert) {
//for every user in trigger.new do whats in the bracket (known as loop)
for (User thisuser : Trigger.new) {
//companyname field is apre ltd (is possible to add more values)
thisuser.companyname = 'aspre ltd';
}
}
notes:
trigger - starting point for all triggers
addcompanyname - name of trigger can be anything
user - sobject for a full list of standard salesforce objects and for a full list of object refeence
before insert - trigger will fire before record inserted/created in database for list of trigger operations
thisuser - variable that represent each specific user in the loop as it iterates one by one across all users in the list trigger.new
trigger.new -returns a list of the new versions of the sObject recordsthat are captured in trigger. this list only available in insert/update triggers and record can only be changed in before triggers for list of trigger context variables
Unit Test for basic trigger
every trigger requires a unit test to push code from sandbox to production -Salesforce requires at least 75% of your code to be “tested” before deploying
tests what the code should do
//all tests start with @isTest
@isTest
//this line defines the class method access and name (for tests below will never chnge)
public class test_addcompanyname
static testMethod void insertNewUser() {
// how to instantiate new user
User userToCreate = new User();
// create all mandatory fields
userToCreate.FirstName = 'Iain';
userToCreate.LastName = 'Banks';
userToCreate.Email = 'iain.banks@email.com';
userToCreate.Username = 'iain.banks@email.com.sandbox';
userToCreate.Alias = 'ilearnapex';
userToCreate.ProfileId = '00ei0000000rTfp';
userToCreate.TimeZoneSidKey = 'America/Denver';
userToCreate.LocaleSidKey = 'en_US';
userToCreate.EmailEncodingKey = 'UTF-8';
userToCreate.LanguageLocaleKey = 'en_US';
// we explicitly insert our user into our Salesforce database using this DML code otherwise it will not eneter the dsatabase
insert userToCreate;
}
}
notes
@isTest – this tells Salesforce we’re writing test code
test_addcompanyname - name of test class
testMethod – this tells Salesforce once again that we’re doing a test
insertNewUser – the name we gave our test method.
User – the API name of any Salesforce sObject, in this case, the standard User object.
userToCreate – the variable we named to store our user record.
’00ei0000000rTfp’ – this is the ID of the profile we’ll give to our user. Note that your org will have different IDs. 15-digit record IDs can be found in the URL of any record. Like text, IDs need to be wrapped in single quotes.
insert – the DML statement to “create” a record in an org. The record only exists in our code until we save it using DML.
