Hi madan, Its the concept of abstraction. Ofcourse we knew that abstarction is achieved by "Abstract" keyword. So both are same. Just their way of using in statement makes the differ. Thank you.

Hello Reva For Finally Block https://www.geeksforgeeks.org/c-finally-keyword/ \ Don’t get confused with Abstraction and abstract class both are different. Abstraction: One among the four types of OOPS concept. It means hiding the complexity of an object by means of composition(sub-dividing) and aggregation(joining). Abstraction is known as Has-A relation e.g. Student has a name, student has a pen, car has one engine i.e. everyone is having Has-A relation. Suppose we have a class Student ,so when we make a program using Has-A relation we will make other classes like address, pen, name (composition i.e. sub dividing its parts ) and then in Student will make an object of each class and will access student features and also its own features , thus removing complexity and hence no confusion will be there. Abstract class: Abstract means what you feel but u dont know what to say. e.g. u are making an application for game and you want your player to kick in game whenever you press 5 button so u will make a method named as kick but the thing is u dntknw what to write a code so u just make a method unimplemented and will declare it or implement it in other class and hence the class having unimplemented methods is written as abstract.REMEMBER: Abstract class can have both implemented and no-implemented methods and we cannot make an object of abstract class

Hi Reva, No need to gets confused Both are same. Finally : Irrespective of interruption of the application by the exception, the code(which is inside finally block) gets executed. Thank you.
