In Object-Oriented Programming, abstraction is the process of hiding unnecessary details and showing only essential information. To implement abstraction in real code, we use: These tools help create structured, flexible, and reusable code where we define what to do, but…
Understand Composition and Aggregation in Object-Oriented Programming. Learn the “has-a” relationship, difference between inheritance and composition, and explore real-world examples like Car and Engine in C++ and Java. Introduction So far, we’ve learned about Inheritance (the is-a relationship) where a…
Learn about Exception Handling in Object-Oriented Programming. Understand the difference between errors and exceptions, master try-catch blocks, and explore how to create custom exception classes in C++ and Java with examples. Introduction In programming, errors are unavoidable but how we…
Polymorphism: Compile-time and Run-time Learn Polymorphism in Object-Oriented Programming, including compile-time and run-time types. Understand method overloading, method overriding, virtual functions in C++, and dynamic binding in Java with practical coding examples. What is Polymorphism? Polymorphism comes from two Greek…
Inheritance in Practice Dive into Inheritance in Practice with real examples of method overriding, constructor chaining, and base class access. Learn how to use the super keyword and understand how constructors behave in inherited classes in both C++ and Java.…
Inheritance: Concept and Syntax Learn the concept and syntax of Inheritance in Object-Oriented Programming. Understand the need for inheritance, how base and derived classes work, and how the “is-a” relationship improves code reusability using practical C++ and Java examples. What…
