What are the correct statements on final key word?Select one or more:The final class is complete in nature and it can be sub-classed or inheritedfinal method and it cannot be overridden in the subclassFinal is a keyword or reserved word in Java and can be applied to member variables, methods, class and local variables in Java.Once you make a reference final you are not allowed to change that reference and compiler will verify this and raise a compilation error if you try to re-initialized final variables in Java
Solution
The correct statements about the final keyword in Java are:
- Final is a keyword or reserved word in Java and can be applied to member variables, methods, class and local variables in Java.
- Once you make a reference final you are not allowed to change that reference and compiler will verify this and raise a compilation error if you try to re-initialized final variables in Java.
The incorrect statements are:
- The final class is complete in nature and it can be sub-classed or inherited. This is incorrect because a final class in Java cannot be subclassed or inherited.
- Final method and it cannot be overridden in the subclass. This statement is incomplete. If it said "Final is a keyword that can be applied to a method and it cannot be overridden in the subclass," it would be correct.
