  Abstraction used to hideunnecessary information and display only necessary information to the users interacting
• 11.
  Abstract Class ● Isa Partial Implementation for Other Classes [Concrete Class] ● You Can’t Create Object [Instance] from Abstract class , Because it is not Fully implemented
• 12.
  C# Keywords IndicateThe Accessibility Scope What You Can Write Inside The Abstract Class : 1. Attribute 2. Property 3. Function 4. Event 5. Abstract Method 6. Abstract Property Abstract Class

  Interface ● Code ContractBetween 2 Developers Abstract Class ● Partial implementation for Other Classes.

  Static [Class , Method, Constructor , Property , Attributes]
• 15.
  C# Keywords IndicateThe Accessibility Scope ● is a just Container For Static Members [Attribute, Property, Constructor, Method] and Constants ● You Can't Create Object From This Class (Helper Class) ● No Inheritance for this Class Static class
• 16.
  C# Keywords IndicateThe Accessibility Scope ● Class Member Method Called Through Class ● The Result Of Calling Method Won't Differ By The Difference Of The Object State [Data] Static Method
• 17.
  Static Property [ClassMember Property] Must Return One Of These: 1. Static Attribute 2. Constant Static Property Compiler Will Initialize the Static Attribute With The Default Value of Its Datatype Static Attribute

  Usages Of Class 1.Call Static Method or Static Property 2. Create Object From This Class 3. Create Object From Another Class Inheriting From This Class ● Static Constructor [Maximum Only One Static Constructor Per Class]. ● Can't Specify Access Modifiers or Parameters for Static Constructor . ● Will be Executed Just Only One Time Per Class Lifetime Before the first Usage of Class . Static Constructor
