The terms 'super' and 'this' are really important when we talk about polymorphism in object-oriented programming (OOP).

What Do 'this' and 'super' Mean?

1. 'this' Keyword:

   • 'this' points to the current object of the class you’re working with.
   • It helps tell the difference between a class’s variables and the inputs you give to methods.
   • It makes it clear when you’re calling methods in the same class.

2. 'super' Keyword:

   • 'super' points to the parent class or the class above the current one.
   • It lets you use methods and properties from the parent class.
   • It's really important to call methods that have been overridden to keep polymorphism working correctly.

How They Help with Polymorphism

• Dynamic Method Resolution:

  • In OOP, you can change (or override) methods. For example, if Class B gets its properties from Class A, and both have a method called display(), when you call display() on an object of Class B, it will use B's version.
  • The 'super' keyword helps you call the version from Class A, which keeps things clear and organized.

• Avoiding Confusion:

  • When two methods have the same name, 'this' helps to clear things up within the class.
  • It makes sure the right variable is being used, which helps with keeping things running smoothly.

Some Cool Facts

• Inheritance Use:

  • A survey of 1,000 software developers found that about 82% of them use inheritance in their work. This shows how much they depend on OOP methods.

• Benefits of Polymorphism:

  • Research shows that using polymorphism can make code about 20-30% simpler. This makes it easier to maintain and work together with others.

By knowing how to use 'super' and 'this', developers can write clearer code, make it easier to manage, and really take advantage of polymorphism in object-oriented programming.
