Selenium WebDriver with Java - Basics to Advanced and Frameworks - Final Keyword in Java

The video tutorial covers the use of the 'final' keyword in Java, explaining its application in variables, classes, and methods. It highlights how 'final' makes variables immutable, prevents class inheritance, and stops method overriding. The tutorial also distinguishes between 'final' and 'finally', emphasizing their different roles in programming. Additionally, it reviews other important keywords and concepts, providing practical examples to aid understanding.

What is the primary purpose of using the 'final' keyword with a variable?

• To allow the variable to be changed multiple times

• To prevent the variable from being changed once assigned

• To make the variable accessible from other classes

• To enable the variable to store multiple data types

What happens when a class is declared as 'final'?

• It cannot be extended by other classes

• It cannot be instantiated

• It can only contain final methods

• It can be extended by other classes

Why would you declare a method as 'final'?

• To allow it to be overridden in subclasses

• To make it accessible only within its own class

• To prevent it from being overridden in subclasses

• To ensure it can only be called once

Which keyword is related to exception handling and should not be confused with 'final'?

• finally

• catch

• throw

• try

What is the role of the 'finally' block in exception handling?

• To execute code only if no exceptions occur

• To execute code regardless of whether an exception occurs

• To catch exceptions that are not handled

• To define a new exception type

Which access specifier allows a class member to be accessible only within its own package?

• protected

• private

• default

• public

What is a key benefit of learning programming concepts through practical examples?

• It allows for better application in real-world scenarios

• It helps in memorizing theoretical definitions

• It reduces the need for practice

• It simplifies complex concepts into single-line explanations
