Object-Oriented Programming Concepts

The foreach keyword represents a loop that iterates over a collection of objects, such as an array or a list.

UML Relationships

In UML, a one-way interaction or usage between objects is represented by the Dependency relationship.
A Dependency relationship in UML represents a one-way interaction or usage between objects.

UML Dependency Relationship

The main purpose of making a dependency relationship weaker in UML is to reduce coupling between objects.

Classes in OOP

The primary role of a class in the context of object-oriented programming is to define a blueprint or template for creating objects.

OOP Pillars

The pillars of OOP do not include "Data Hiding" as one of them.

Inheritance Limitations

In most programming languages, multiple inheritance is not allowed with inheritance.

Authors and Resources

Alexander Shvets is the author of the book 'Dive Into Design Patterns' and the online course 'Dive Into Refactoring'.

Inheritance Disadvantages

A disadvantage of inheritance in OOP is that it can lead to the "Fragile Base Class Problem", making the subclass dependent on the superclass.

Software Design

The concept that defines the universal principles and patterns of software design that are considered good, proven, and reusable is called Design Patterns.

Abstraction in OOP

Abstraction in OOP refers to the process of showing only the necessary information to the outside world while hiding the internal details.

Encapsulation in OOP

Encapsulation in OOP refers to the concept of bundling data and methods that operate on that data within a single unit, called a class or object.
