• By default all the variables and methods are non-static.

• Scope of the non-static variables or methods is within the scope of the same object.

• We can declare variables and methods as static by using static keyword.

• Scope of the static variables and methods is throughout the transaction.

• Static variables and methods, we can directly call with class name (we cannot access static variables and methods with object name).

//Map holds key and value pair.

//Syntax: Map mapName = new Map();

/*Map countryISTCodeMap = new Map();

//map keys are case-sensitive.

keyset(): To fetch only keys from the map.

values(): To fetch only values from the map.

containsKey(value): To search a key from the map.

get(key): By supplying the key we can fetch the value.

put(key,value): To add key and value in a map.

Triggers - Best Practices in Salesforce

Trigger Scenarios:- (Prepared By Suresh Kumar tvs)

Scenario one:-  (All Opportunity Triggers)

//Trigger to display error message when stage name is change from 'Order closed' to other values

Part one 1 (While trigger.old) :- 

if(Trigger.isupdate && Trigger.isBefore){

          for(Opportunity oldOpportunity:trigger.old){

             if(oldOpportunity.StageName == 'Order Closed'){

                  trigger.new[0].addError('An Opportunity cannot be edited once the opportunity stage is Order Closed');

             }

          }

Part 2(While Trigger.new):-

if(Trigger.isupdate && Trigger.isBefore){

set<id> opplistid=new set<id>();

                for(Opportunity newopportunity:Trigger.new){

                    opplistid.add(newopportunity.id);

                }

                list<Quote> Qlist = [select OpportunityId,Customization_Payment_Criteria__c,Approval_Status_Quote__c from Quote where OpportunityId=:opplistid];

                for(Opportunity newopportunity: Trigger.new){

                 Opportunity old=trigger.oldmap.get(newopportunity.Id);

                    if(newopportunity.Record_Type_Name__c=='Watches' || newopportunity.Record_Type_Name__c=='Jewellery'||newopportunity.Record_Type_Name__c=='Lifestyle'){

                            for(Quote qq:Qlist){

                                if(qq.OpportunityId==newopportunity.id && qq.Customization_Payment_Criteria__c =='Free Of Cost' && qq.Approval_Status_Quote__c!='Approved'){

                                    newopportunity.addError('cannot change Stage as Quote Customization Payment Criteria is Free of cost and quote is not approved');
