Vehicle Toll Calculation System Problem: Develop a system to manage toll collection for various types of vehicles. Implemant the following base class framework: class Vehicle { protected: string registrationNumber; public: Vehicle(string regNum) { registrationNumber = regNum; } virtual int calculateToll() = 0; // Calcula ...

Encapsulation Encapsulation is a core principle of object-oriented programming that bundles data and methods within a single unit while restricting direct access to internal state. It acts as a protective barrier, ensuring controlled interaction through well-defined interfaces. Example of Encapsulation A common implementation uses private field ...

The decorator pattern is widely used to dynamically add responsibilities to objects without altering their existing structure. This example demonstrates how to enhance a basic home security sensor incrementally: from a simple audio-alerting sensor to a comprehensive system with vibrations and strobe lights. Abstract Class: HomeSensor Defines th ...

The Decorator Pattern is a structural design pattern that allows behavior to be added to individual objects, either statically or dynamical, without afffecting the behavior of other objects from the same class. It emphasizes composition over inheritance and adheres to the Open/Closed Principle: open for extension, but closed for modification. A ...

The java.lang.Object class serves as the root of the entire Java class hierarchy. Every user-defined class, as well as built-in classes, inherits directly or indirectly from this base class. Because it is the ultimate ancestor, the methods defined within Object are available to all Java objects. Key Methods in the Object Class The following met ...

Java allows defining classes within other classes or methods, known as inner classes. These include member, local, anonymous, and static inner classes. Member Inner Classes A member inner class is defined with in another class and has access to all members of the outer class, including private and static members. class Shape { private doubl ...

Operator Overloading in C# Operator overloading enables custom behavior for operators when working with user-defined types. Key aspects include: Only applicable to classes and structs Implemented through static methods named operator followed by the symbol (e.g., operator +) Must be members of the class/struct they operate on Syntax Patterns ...

Core Python Data Types Python supports multiple fundamental data types. Numeric types include integers (int), floating-point numbers (float), and complex numbers (complex). The string (str) type handles textual data. Sequence types such as lists (list) and tuples (tuple) store collections of elements. Dictionaries (dict) provide key-value pair ...

Encapsulation is the process of bundling data (attributes) and operations (methods) together, with the data protected internally so that only authorized operations can modify it. Objects should encapsulate relevent data and provide corresponding behaviors. Benefits include: Hiding implementation details: methods (e.g., connecting to a database ...

Part 1: Theoretical Knowledge The eleventh week of study focused on Java's Collections Framework, building upon the generic programming concepts covered in the previous week. The theoretical foundation centered on understanding various collection classes, their interfaces, and implementation strategies in Java. The Java Collections Framework pr ...
