Which of the following statements about the `final` keyword with primitive variables is true?

  1. It makes the variable immutable in all contexts.

  2. It prevents the variable from being assigned more than once.

  3. It makes the variable a constant expression only if assigned at declaration.

  4. It cannot be used with primitive types.

  5. It allows the variable to be assigned only in a static context.

Show answer & explanation

Correct answer

It prevents the variable from being assigned more than once.

Explanation

A `final` primitive variable cannot be reassigned after initialization. However, if it is an object reference, the object's state can change, but the reference itself cannot be changed. Thus the statement about reassignment is correct.
