Java MCQ: What does the ‘final’ keyword do in Java?
a) Prevents method overriding
b) Prevents inheritance
c) Prevents variable reassignment
d) All of the above
Answer:
d) All of the above
Explanation:
The final keyword in Java can be used to prevent method overriding, inheritance, and variable reassignment. When applied to a class, it prevents subclassing; when applied to a method, it prevents overriding; and when applied to a variable, it makes the variable constant.
Understanding the final keyword is crucial for controlling how classes and methods are extended or modified.
