Inheritance in Object-Oriented Programming (OOP) is similar to how families pass down traits from parents to children. In OOP, inheritance lets a new class, called a subclass, get features and actions (known as methods) from an already existing class, which is called a superclass.
This helps create a clear structure and allows programmers to build on what they have already written.
Let’s say you’re making a program for a university that has different types of students. You could start with a general "Student" class that includes details like name, ID, and degree. Then, when you make a subclass called "GraduateStudent," it gets all the features from the "Student" class. You can also add unique things for graduate students, like their thesis topic or how many publications they have.
Here’s the important part: Inheritance helps reuse code in several important ways:
Less Repetition: Instead of writing the same code in every subclass, you write it once in the superclass. This makes your code cleaner and easier to manage.
Simpler Updates: If you want to change something that many classes share, you just update the superclass. All the subclasses will automatically use the new version.
Polymorphism: This lets subclasses act like their superclass. You can use a subclass where a superclass is expected, which makes your code more flexible.
Overall, inheritance makes programming easier, helps to reduce mistakes, and speeds up the coding process by allowing the smart reuse of existing code.
