What’s the Liskov Substitution Principle?
Explore the Liskov Substitution Principle, which ensures that derived classes can replace parent classes without altering program behavior. Understand its significance in inheritance, how it prevents issues caused by overridden methods in subclasses, and why it is essential for maintaining reliable and predictable software design.

The Liskov substitution principle was initially introduced by Barbara Liskov, an American computer scientist, in 1987. The principle states that if you substitute a parent with any of its derived classes, the behavior of the program shouldn’t change.
This principle was introduced specifically with inheritance in mind, which is an integral feature of object-oriented programming. Inheritance allows us ...
