OOP Concepts

What is OOP??? 👇 OOP stands for Object-Oriented Programming and that concept is a programming paradigm based on the concept of "Objects" that contain data and methods. The main purpose of object-oriented programming is to increase the flexibility and maintainability of programs. Modularity for easier troubleshooting, reuse of code, flexibility, and effective problem solving are advantages of the OOP concept.   Now, let us consider what an object is... An object is anything that has state and behavior. For example, a car, a dog, a person, etc. At runtime, when the Java Virtual Machine (JVM) encounters the new keyword, it will use the appropriate class to make an object that is an instance of that class. Consider the car object it has state color, model, brand, weight, and as behaviors we can consider a break, accelerate, gear change.

Stack data structure

Welcome to  imalshablog.blogspot.com . In my first blog, I decided to write about the stack data structure. It is a very easy and basic data structure as well as it is a linear data structure. A stack is a list of elements in which an element may be inserted or deleted only at one end, called the top of the stack. The insertion or deletion is happened according to the  LIFO principle.  LIFO stands for Last-In-First-Out. Mainly, there are five basic operations have in the stack. Push -: This operation is used for inserting an element in the stack.        Before happening push operation, check whether the stack is full. if the stack is full, display the error message and exit. if the stack is not full, increment top to point next empty space and inserts the next element to stack top.  Push Algorithm       IF top = max - 1           print overflow      END IF ...
