What are some common mistakes with polymorphism in programming?

What are some common mistakes with polymorphism in programming?

Some common mistakes include misunderstanding method overriding, not using the correct access modifiers, and failing to recognize when to use polymorphism.

Can you explain method overriding and why it's important?

Method overriding allows a subclass to provide a specific implementation of a method that is already defined in its superclass. It's important for achieving runtime polymorphism.

What about using the wrong access modifiers?

Using the wrong access modifiers can prevent polymorphic behavior. For example, if a method in a subclass is marked as private, it won't override the superclass method.

How can I avoid these mistakes?

To avoid these mistakes, always ensure you understand the principles of inheritance, use proper access modifiers, and test your code thoroughly.
