----------------------------------------------
Conclusion:
Result is not dependent on what the sharing contaxt of Main Class it depends on what the sharing contaxt of the class in which SOQL is executing

 Lets do some more exercise:
------------------------------------------------------------------------
create an other class:
public virtual without sharing class WithoutSharingContaxt
{


}
-------------
and
-------------
public with sharing class AccountsWithSharing extends WithoutSharingContaxt 
{
  public  static  List<Account>  getAccountsWithSharing()
    {
          return [Select id,name from Account];
    }
}
------------------------------
then lets check the output

------------------------------------------------------
Conclusion:
HA HA what the difference here!
If current class contaxt is forced  to with sharing we can not extend its contaxt to without sharing

 Lets remove  that forced with sharing  keyword
--------------------------------------
public  class AccountsWithSharing extends WithoutSharingContaxt 
{
  public  static  List<Account>  getAccountsWithSharing()
    {
          return [Select id,name from Account];
    }
}

 ------------------------------------------------------
Conclusion:
HA HA what the difference here!
we can  extend  the current class contaxt to without sharing only if no sharing contaxt(with sharing or without sharing) is  specified

 Hope with and without sharing thing is more to understand here!

Convert a Lead to person Account


If your organization uses person accounts, 
you can convert leads to either person accounts or business accounts. 
Leads with a blank Company field are converted to person accounts. 
The default person account record type for your profile is applied to the new person account. 
Note that you can only create leads with a blank Company field using the Force.com API. Leads with a value in the Company field are converted to business accounts. The default business account record type for your profile is applied to the new business account.

As a best practice, use different lead record types and page layouts to differentiate leads that will be converted to person accounts from those that will be converted to business accounts. 
In particular, remove the Company field from the page layouts of leads(So that it can be blank) that will be converted to person accounts, and make the Company field required on the page layouts of leads that will be converted to business accounts.

java.lang.Integer

[COPIED]-https://www.tutorialspoint.com/java/lang/java_lang_integer.htm

Introduction

The java.lang.Integer class wraps a value of the primitive type int in an object. An object of type Integer contains a single field whose type is int.

Class Declaration

Following is the declaration for java.lang.Integer class −
public final class Integer
  extends Number
    implements Comparable<Integer>

Field

Following are the fields for java.lang.Integer class −
  • static int MAX_VALUE − This is a constant holding the maximum value an int can have, 231-1.
  • static int MIN_VALUE − This is a constant holding the minimum value an int can have, -231.
  • static int SIZE − This is the number of bits used to represent an int value in two's complement binary form.
  • static Class<Integer> TYPE − This is the class instance representing the primitive type int.

Class constructors

S.N.Constructor & Description
1
Integer(int value)
This constructs a newly allocated Integer object that represents the specified int value.
2
Integer(String s)
This constructs a newly allocated Integer object that represents the int value indicated by the String parameter.

Class methods

instanceof Operator

instanceof Operator :

Here's an example of instance of operator.
class instanceofOperator {
    public static void main(String[] args) {
     
     String test = "asdf";
     boolean result;
     
     result = test instanceof String;

Unary Operators

Unary operator performs operation on only one operand.

How to get all component's attributes value by one call of component.get();

In This article,I explained how to set all component's attributes value by one call.
In the similar way we can get all the componets values by one call of componet.get()

 <!--- Lightning Component  ---->
<aura:component>
<aura:attribute name="map" type="Map" default="{str1:null,str2:null,obj:null}"/>
<aura:attribute name="str1" type="String"  default="{!v.map.str1}"/>
 <aura:attribute name="str2" type="String" default="{!v.map.str2}"/>
 <aura:attribute name="obj" type="Contact" default="{!v.map.obj}"/>
</aura:component>




------------Lightning Component Controller--------------------------
fn: function(cmp, event, helper)
    {
        var map=cmp.get("v.map");//top or START of function
           console.log(map.str1);
           console.log(map.str2);
       
}
