What is the final keyword in C#?
In c# there is no keyword like “final” but the same thing is achieved by keyword “sealed“ . A class which is marked by keyword sealed cannot be inherited.
What is the use of final keyword give example?
The final keyword is a non-access modifier used for classes, attributes and methods, which makes them non-changeable (impossible to inherit or override). The final keyword is useful when you want a variable to always store the same value, like PI (3.14159…). The final keyword is called a “modifier”.
What is final keyword?
What is the Final Keyword in Java? Java final keyword is a non-access specifier that is used to restrict a class, variable, and method. If we initialize a variable with the final keyword, then we cannot modify its value. If we declare a method as final, then it cannot be overridden by any subclasses.
Does C# have final keyword?
Java has a final keyword, but C# does not have its implementation. When you use sealed modifiers in C# on a method, then the method loses its capabilities of overriding. The sealed method should be part of a derived class and the method must be an overridden method.
What is sealed in C#?
Sealed classes are used to restrict the users from inheriting the class. A class can be sealed by using the sealed keyword. The keyword tells the compiler that the class is sealed, and therefore, cannot be extended. No class can be derived from a sealed class.
How do you declare a final variable in C#?
Java has a final keyword, but C# does not have its implementation. Use the sealed or readonly keyword in C# for the same implementation. The readonly would allow the variables to be assigned a value only once.
What is final keyword in oops?
The final keyword is used to prevent a class from being inherited and to prevent inherited method from being overridden.
What are the three uses of final keyword explain with example?
Final keyword in Java has three different uses: create constants, prevent inheritance and prevent methods from being overridden.
What is final method?
The final modifier for finalizing the implementations of classes, methods, and variables. We can declare a method as final, once you declare a method final it cannot be overridden. The main intention of making a method final would be that the content of the method should not be changed by any outsider.
Can final method be overloaded?
private and final methods can be overloaded but they cannot be overridden. It means a class can have more than one private/final methods of same name but a child class cannot override the private/final methods of their base class. Argument list should be different while doing method overloading.
What is final in C?

Which is the final keyword in C #?

When to use final in a class definition?
When used in a class definition, final specifies that this class may not appear in the base-specifier-list of another class definition (in other words, cannot be derived from).
