Can we override method in child class?

How do you prevent a method from being overridden in a child class?

Similarly, you can prevent a method from being overridden by subclasses by declaring it as a final method. An abstract class can only be subclassed; it cannot be instantiated. An abstract class can contain abstract methods—methods that are declared but not implemented.

Can you prevent overriding a method?

The final way of preventing overriding is by using the final keyword in your method. The final keyword puts a stop to being an inheritance. Hence, if a method is made final it will be considered final implementation and no other class can override the behavior.
