What is object-oriented implementation?

The implementation of objects must adhere to the principles of object-oriented methodology. The most important aspect of implementing objects is providing a mechanism for dynamically selecting the method to implement a message response. In a class-based OOL objects are instances of and created by classes.

What is abstraction in OOP with example?

Abstraction means displaying only essential information and hiding the details. Data abstraction refers to providing only essential information about the data to the outside world, hiding the background details or implementation. Consider a real life example of a man driving a car. This is what abstraction is.

It promises to reduce development time, reduce the time and resources required to maintain existing applications, increase code reuse, and provide a competitive advantage to organizations that use it.

How does OOP work in an ATM machine?

The ATM will use this instance to do the balance queries and modifications. At the end of the process, when the customer gets his/her credit card back, the ATM machine should send the Customerobject back to the bank so it can update its internal records. Translating this into OO design.

How is the state pattern used in ATM?

Since ATM class functions as a finite-state machine, we can incorporate the State design pattern The State pat­tern sug­gests that we cre­ate new class­es for all pos­si­ble states of an object and extract all state-spe­cif­ic behav­iours into these classes.
