I am a working professional in mnc company I have 3 years of experience in giving salesforce admin development...
//Map holds key and value pair.
//Syntax: Map mapName = new Map();
/*Map countryISTCodeMap = new Map();
countryISTCodeMap.put('India','91');
countryISTCodeMap.put('USA','001');
countryISTCodeMap.put('India','911');//replaces old value with new value.*/
Map countryISTCodeMap = new Map{'India'=>'91','USA'=>'001', 'India'=>'911'};
system.debug('countryISTCodeMap result: '+countryISTCodeMap+' with size '+countryISTCodeMap.size());
system.debug('countryISTCodeMap keys: '+countryISTCodeMap.keyset());
system.debug('countryISTCodeMap values: '+countryISTCodeMap.values());
system.debug('countryISTCodeMap search: '+countryISTCodeMap.containsKey('India'));
system.debug('countryISTCodeMap fetching value based on key: '+countryISTCodeMap.get('India'));
//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.

Difference Between Insert/Update And Database.Insert/ Database.Update
Kumar
I am a working professional in mnc company I have 3 years of experience in giving salesforce admin development...
insert/update
Database.insert/Database.update
Assume that you are inserting 100 records. If any one of the record fail due to error then entire operation will fail. None of the records will be saved into the database. with insert/update if we use try-catch then we can capture only one error which will cause to stop the operation.
Assume that you are inserting 100 records. If any one of the record fail due to error then it will perform partial operation (valid records will be inserted/updated) if we use Database.insert(list,false)/ Database.update(list,false).
.with Database.insert/Database.update we can capture all the errors by saving result in Database.saveResult[].

What is Mixed-DML-Operation Error And How To Avoid?
Kumar
I am a working professional in mnc company I have 3 years of experience in giving salesforce admin development...
If we perform DML operation on standard/custom object and global objects(User, UserRole, Group, GroupMember, Permission Set, etc...) in same transaction this error will come.
To avoid this error, we should perform DML operation on standard/custom object records in a different transaction.
In general all the apex classes and apex triggers execute synchronously (execute immediately).
If we perform DML operation on standard/custom object records asynchronously (execute in future context), we can avoid MIXED-DML-OPERATION error.
To execute logic asynchronously keep the logic in an apex method (in a separate apex class, not in same apex trigger) which is decorated with @future annotation.
See the below example:
Note: To analyse the code copy it and paste it in notepad for the convenience.
public class TriggerUtility {
/*
1. Following future method execute asynchronously (whenever server is free it will execute in future context).
2. We should not declare @future method in Apex Trigger.
3. @future method should be always static.
4. @future method accepts only primitive data types (Integer, String, Boolean, Date, etc...) as parameters and it won't accept
non-primitive data types (sObject,Custom Objects and standard Objects etc.. ) as parameters.
5. @future method should not contain return type. Always it should be void.
6. From an apex trigger we can make only make asynchronous call outs. To make call out we should include "callout = true" beside the future @annotation.
7. We cannot perform synchronous call outs from Apex Trigger.
*/
//Below is the example for the future method -
@future(callout = true)
public static void processAsync(primitive parameters) {
//Logic to insert/update the standard/custom object.
}
}
