Difference Between Pop And Oop In Java
In Java, “pop” typically refers to stack-based memory management while “oop” refers to object-oriented programming. Stack-based memory management in Java involves using a Last-In-First-Out (LIFO) data structure for method execution and variable storage, where function calls and local variables are managed. On the other hand, object-oriented programming in Java focuses on creating classes and objects to model real-world entities, with emphasis on concepts like inheritance, polymorphism, and encapsulation. While stack-based memory management and object-oriented programming are different concepts in Java, they both play important roles in defining the behavior and structure of Java programs.

1 - In POP (Procedural Oriented Programming), the emphasis is on procedures and functions to manipulate data, while in OOP (Object Oriented Programming), the focus is on objects that contain data and methods to manipulate that data.
2) POP follows a top down approach, where a program is divided into procedures or functions, while OOP follows a bottom up approach, where a program is divided into objects and classes.
3) In POP, data is separated from the functions that operate on it, while in OOP, data and methods to operate on that data are encapsulated within objects.
4) POP lacks concepts such as inheritance, encapsulation, and polymorphism, which are core features of OOP.
5) OOP promotes reusability of code through the use of classes and objects, while POP often leads to redundant code due to its procedural nature.
6) In OOP, objects communicate with each other by sending messages, while in POP, data is often passed between functions as parameters.
7) OOP provides better code organization and maintenance due to its modular and reusable components, while POP can lead to spaghetti code if not structured properly.
8) OOP allows for easy modification and extension of code through inheritance and polymorphism, while POP requires more manual effort to make changes.
9) OOP encourages a more intuitive and realistic representation of the problem domain through modeling real world objects, while POP may not always represent the problem domain as accurately.
10) OOP promotes the concept of data hiding, where the internal implementation details of an object are hidden from the outside world, leading to better security and abstraction, while in POP, data is often exposed.
